Error code :0x800C0155, 2 - Windows Live Mail 2011 will not open

Anonymous

I just recently got ride of a trojan problem and everything was working perfect until this evening. Since I got rid of it I keep seeing a Run.DLL error popping up when I log in (something about "qxnuprzc.dll" is missing with nothing about it showing up in web searches) but everything else is in working order. Sometime around 3pm I had my Firefox browser open and was playing a game. When I closed the game firefox was gone, so I clicked the icon to open it back up but it gave me an error; something about it was being used by another program.

I did some searching and was able to delete a file within the AppData folder but it gave me a new problem. So I had to rework the profile directory for Firefox and create a new profile, delete the old one, and change the text in a ".INI" file to change the default profile and it's location. Now I got my browser working, but not before I went hunting for a solution using explorer 9, which had it's own problem forcing me to change the search engine-whatever to another one; default was "bing!"

So now I am looking at error code: 0x800C0155, 2 and I noticed as well that the gadget, Feed headlines 1.1.0.0, cannot find any headlines. That error code tells me this:

Windows Live Mail could not be started. The application was unable to open the Windows Live Mail message store. Your WLM mailbox data is currently being used by another program, such as a virus scanner. Close the program or wait for it to complete its operation, then open WLM again. (0x800C0155, 2)

Same problem as before with firefox, I got a program using "my" programs and it's not something I am doing. I do have Norton but it has not updated today nor has it ever caused a problem. Repair does not work, nor does reinstalling.

My original problem was that I could not send email.

In reading these forums and trying to solve the problem, I have created a new issue. I can no longer open my mail program. I started with Windows Live Mail 2011, and now have Windows Live Mail 2012, which will still not open. I get this message:

I have just finished a current windows update, have run a malware program scan and am now ready try something else.

I would appreciate any assistance with this that I can get.

Thank You
