Ok so I fixed it!!!!!!!!!!!!!!!!!!!!!!!!!!!!! for now. All I did was go into IE internet options. Under trusted sites I typed http://www.netflix.com
Found that on another forum and thought "thats too easy" and afterwards I loaded a netflix movie. Freaking stupid! I have been at this for days. And thats all it was? Im sure a new problem will arise. Good luck. Let me know if that works for you.
Still no good. I put every version of netflix, https, http, *.netflix, movies.netflix.com, www.netflix.com into the trusted site box. Same message. Uninstalled and reinstalled. Same message. Firefox. Same message. iexplore as administrator. Same message.
Deleted cached files. Enabled download. Run As Admin. Nothing works.
WHAT IS IT?!?!?!? Years of netflix working just fine, and now AARGHH!
How To fix
Find and delete the file mspr.hds
Enjoy your movie
