TRAINING.dat -> CABINFEVER.dat

Alright, so I used WinRezLT.exe to extract the WORLDS.rez file from the Combat Arms Game folder.

I renamed CabinFever.dat as Training.dat.

I copied the cabin fever map dat file over the training grounds dat file.

I injected the new dat file into the worlds.rez with RezInject.

I took out the new rez file, renamed it on the desktop, putting it in its own folder.

I removed the old worlds.rez file from the game folder.

Then I entered the game, alt tabbed out, put my modded worlds.rez file in the game folder and then entered training mode.

The game crashed to desktop. Where did I go wrong?

Wrong file, duh. I needed GMS.rez, not WORLDS.rez. Lemme see if it works...

NOPE, that didn't work, either. Do I have to change both files? Let me see...

Replacing both worlds and gms rez files didn't work either. Can anyone help me with this? Is it still possible?
