The JSGME.exe that was in the YW001.rar is not corrupted, it's you.
For those of you who already have JSGME, just put YW001 into your "MODS" folder.
For those of you who
don't already have JSGME.exe, put it into your Doomsday/Armageddon root folder, double-click (if you have Vista or Win7, you must "run as administrator"), the program creates a new folder (default: "MODS") where you put YW001.
Activate by selecting the mod in the left row, press the ">" button and you're ready to go once you have patched HOI2.exe.
To patch HOI2.exe, just click on the patcher, select english languange (so you press the correct button) and choose HOI2.exe and press patch. If you have Win7 or Vista, you might need to run the patcher as "run as administrator".
Otherwise, if it still doesn't work, tell me what you're specs are (XP, vista, win7) and post screenshot of where it all goes wrong and I try to help.
