Help: Choosing the right crack file

[Beyon]

I'm a newbie trying to backup my first game (Battlefield 1942). When I search the game in the GameCopyWorld I got a whole list of files. In addition to different version numbers, there are also files like:

No CD/Fixed Exe/Server Fix
Fixed Exe/Server Fix
No CD Patch
No CD Loader
trainer...

I've no idea which one is the right stuff. What I want is a crack file that allows me to play the backup copy in my PC. Please could anyone give me a hand and explain what the above terms (cd loader, fixed exe, patch, trainer, etc) mean.
