Doom 3 V 3.1.1 No Cd Patch Notes
Adding this patch results in the game asking for the Doom 3 CD-Key and it will not accept the key that was entered when it was originally installed from CD. The doomkey file has the original entered key (minus the last two characters). Aug 03, 2004 Too lazy to wait at work until 7pm to get it a Gamestop. Had to finish Far Cry anyway tonight. Got really frustrated with FC and god-mowed through.

No-CD & No-DVD Patch troubleshooting: The most common problem getting a No-CD/No-DVD patch to work is ensuring that the No-CD/No-DVD patch matches you're game version, because the games exe is changed when a patch update is applied previous versions won't work.
If its an older game you are playing and you are running Windows 7 or Windows 8 it may not work, if you right click the .exe file and choose Properties and then Compatibility you can change this to run in Windows 98/ Windows 2000 etc. You can find more information on the Beginners Help page here
