I am not sure what you mean by cracked?
I bought the game - installed all 6 disks and used my legit CD key...
I was then able to run the game fine as singleplayer but when I went to internet to play online, I get a message saying that there is a new patch available - I downloaded that and I think I messed that part up.
I extract the patch to the same destination folder the compressed patch was downloaded to...
Then I get 4 folders that seem to be identical to 4 folders in my ut2004 folder...I was told to delete the old ones in the ut2004 folder and replace them with the new 4 folders from the patch and that was all - I think that is where I messed up if that makes any sence
