problems with PPFMaster

[RNE_GDE]

when i used PPFmaster to add ppf files to a map file it works at first. so i apply them and use the game. but when i want to undo the application of them so i can use old versions it doesnt work. it always fails, so i have to delete the files then reinstall halo. so i dont know why it wont undo my applications, but it someone knows why, please tell me.

Use PPF-O-Mattic. Always make a backup of your original map before you apply your patch.
