a little while ago i made a backup copy of neverwinter nights and it worked perfectly. all of a sudden, however, the play disc has stopped working. my drives are able to read the backup disc and tell me what is on it, but when i go to actually play the game i just get the splash screen and then nothing. nwnmain.exe runs as a process, but never actually loads.
i've tried uninstalling and reinstalling, but to no avail. does anyone have any ideas as to what may have caused my computer to suddenly not be able to play the disc?
