I am still playing with my original copy of UT from 2004 - I hope I'll never lose the disc/key.
Just an update for those who are asking me what to do once you have a new valid key:Once you have a new valid game key you can replace the pirate cd key in your windows registry with a new one using this UT2004RegFix-1.3.zipIf you have linux you need to edit the file with the name cdkey (no extension) in your ~/.ut2004/System/ folder. Put the CD-key in the file exactly as it is printed on the CD case and save the file.
No way - do you really have the Unreal Anthology diamond edition?
I've been looking for the Unreal Anthology diamond edition (tm) everywhere - you are a lucky guy.
