How to use UnSafedisc?



I'm trying to copy Unreal Tournement v400b with UnSafedisc v1.2.2. When it's finished, the programm creates a file named testme.exe. My question: What do I have to do now? Delete UnrealTournement.exe and replace it with testme.exe? And what do I have to do with the *.tmp files? Can anyone out there help me out?!? Tnx!
