My computer has had a problem latetly, I don't know how or why, or when it specifically started, but it can't read any protected game CD's. The games I've tried specifically are Warcraft III Frozen Throne, The Sims, Dawn of War, Counter Strike Source, and Starlancer. It always gives me an error message telling me to insert the original CD, but it is the original CD.
I'm not a computer genius, nor do I claim to be, but I know a fair amount more than the average person. I just have no idea what this is, so I asked my computer teacher. He told me there was software that came packaged with a Splinter Cell game on PC that sometimes caused the problem I have, and he gave me a program that deleted that software. When I ran it, it told me it found no traces of the software on my computer, and I don't own Splinter Cell, nor has it ever been on my PC.
Does anybody know what could be causing this problem?
