Windows Media Player encountered a problem while creating or saving the playlist.

ChuckRenner: exactly, this is a known issue with WMP itself and is not caused by WMP Plus! (at least not as far as I know). The fact that it started occurring after installing the plug-in might have been a coincidence.

Also, the error at startup occurred because WMP Plus! was hitting the same error as when you were manually creating a playlist in WMP.

I also have had problems with media player not creating playlists, and it was a problem with the music library as airwater suggests.  After installing Win8 it, if I looked in to the Music library it was trying to use UNC paths to access the locations (e.g. \<COMPUTERNAME>\Users&lt;USERNAME>\Music)

I had a similar issue, some of my libraries were using UNC file names as well (instead of a local folder).  Worse yet, the paths they were showing were for a computer that is no longer a part of my network.  I'm not sure how they got there, but I suspect it was a side effect of the "Windows Easy Transfer" I used to migrate from a Windows XP Home netbook to this (brand new) Windows 7 Professional notebook.  I no longer suspect "Windows Media Player Plus!" to have been part of the source of the problem.

I also have had problems with media player not creating playlists, and it was a problem with the music library as airwater suggests.  After installing Win8 it, if I looked in to the Music library it was trying to use UNC paths to access the locations (e.g. \<COMPUTERNAME>\Users&lt;USERNAME>\Music)

I shared the user folder, and suddenly when I went into the library - it had started to use the local paths instead (C:....), very bizarre!

Anyhow after that I could suddenly save playlists - so make sure and check you Music Library!!

Limelad, what exactly happens when you try to save a playlist?

I suggest that you try resetting the media library. First note that resetting the library will make you lose all current play counts, and possibly ratings too. Then, follow these steps:

• Reboot the PC.
• Go to Start, type  services.msc in the Search field, and press Enter. In Services, find the Windows Media Player Network Sharing Service . If its status is Started , double-click the service and click  Stop .
• Go to Start, type  %LOCALAPPDATA%\Microsoft in the Search field, and press Enter. This folder will open up in Windows Explorer.
• In this folder, rename the  Media Player folder to something like Media Player old . If you can't see the folder, then it's probably hidden. Set Explorer to show hidden files and folders, and to show protected system files.
• Start WMP, your library will have been reset and will be rebuilt. Check if the issue still occurs.

Tim -

You just happen to be the person I wished to talk to about this EXACT same problem.

Why? Because I did not have this problem until after I installed your program, Windows Media Player Plus!, that I started to have this problem.

I have uninstalled all my media player plugins (including yours), stopped the Windows Media Player Network Sharing Service, deleted the folder %LOCALAPPDATA%\Microsoft\Media Player, deleted the registry keys at [HKEY_LOCAL_MACHINE\Software\Microsoft\MediaPlayer] and at [HKEY_CURRENT_USER\Software\Microsoft\MediaPlayer.

I then ran Windows Media Player, answered all the questions in the setup wizard, opened the player, and tried to create a playlist, and got the same error dialog, "Windows Media Player encountered a problem while creating or saving the playlist."

There is a "Web Help" button on the dialog, but it is worthless.  I found many more possible fixes with a Google search.

Anyway, when I had "Windows Media Player Plus!" installed, whenever I opened the Windows Media Player I got an error message about not being able to add the Party Playlist (or something like that). If I acknowledge the error, I can still use the WMP, but I cannot name playlists.  Uninstalling your plugin did not fix the situation with the playlists.

I would be grateful for any information you could provide on repairing Windows Media Player.

By the way, I love your plugin, because of the only feature I am interested in (being able to pause and play with the spacebar when the WMP is in the foreground).

Again, any help with fixes and/or updates to WMPP! would be apprecaited!

Thank you!

Edit: I managed to resolve the main issue, thanks to reading the post from grant-vz.  Some of my libraries did not have the default save location set.  Once I set them, I was able to created and name playlists in WMP!  Now to reinstall WMPP! and to see if those problems are fixed as well!

Final Edit: After installing Windows Media Player Plus! and doing just a little more tinkering, playlists can now be created, named, saved, and loaded (including the "Party Shuffle".

So the posts here did end up providing me with the solution (specifically the one from grant-vz).
