GTA Vice City won't launch because of this. ):
I've pumped in about 8 hours of gameplay into GTA VC Steam version, and recently, it hasn't been launching.
This program called "Sonic Cineplayer Decoder Pack" is telling me that I'm missing a CD, and the only way to deal with the issue is to force shut down processes with my Task Manager.
I've searched everywhere in my system to find Sonic to uninstall it, but can't.
