I viewed what the problem was, and it said under error signature:
AppName: wmplayer.exe AppVer: 10.0.0.3802 ModName: wmvcore.dll
ModVer: 11.0.5358.4827 Offset: 000f2b22
The dll is corrupted. i found a new one, but when i try to replace the .dll it claims i need a password to replace it.
I tried all the passwords i know, but this is a refurbished computer.
I was wondering whether there is a way to get round the password thing, or just anything to get rid of the pop-up and fix the players!?
Thanks a lot
