Hi Octopia
You could easily have resolved this problem by installing a later version of the .NET framework.
You can get v2 from
http://www.microsoft.com/downloads/d...latedDownloads
and v3 from
http://www.microsoft.com/downloads/d...kInfoContainer
I suggest installing v3.
The ATI stuff is your graphics card drivers and associated files and would have come with the PC unless you installed a graphics card after purchasing the PC. If you delete any of these files you may loose some functionality so I wouldn't recommend it. You should have an ATI CD/DVD that came with your PC for restoring the files in case of a problem, though downloading the latest versions from the ATI website would be wiser.
I imagine that what the game did was update some of your ATI files to the latest versions which require a more up to date .NET framework than you have installed, hence why you are still getting a warning message when you reboot.
There are two ways to rid yourself of the error, reinstall the older versions of the ATI files, or update your .NET framework. I suggest you do the latter.
BTW Can you please address your questions to the forum as a whole as there are other people on here who can help you. Not that I mind the flattery though
