Since The Full Monty came out I've struggled to get it to work. I've uninstalled IL-2 a number of times, and very carefully followed the directions. Time after time I'd find my computer hitting a hard freeze when I'd try to run TFM, using JSGME, so I tried Total Modder, which would also not work- but then on a new start it worked! But there were none of the new aircraft, etc. So after trying any solutions hinted at here, I went back to JSGME, and it really did work with everything!
I've found, time, after time, over many years of modding IL-2, that sometimes I'm doing something wrong and the light bulb will go off when I notice what it is and things finally work. But sometimes I'll do EXACTLY the same thing, with failure the first time- sometimes the first many times- then finally it works, even though I've done the same procedure.
Modded IL-2 has grown gargantuan! It can make it very fussy and cause astronomical frustration, but I've found that instead of letting that frustration get to me, I just keep plugging away, and I've always managed to succeed in the end. So, if anyone is still having trouble, don't give in to the urge to throw your computer out the window. Even after more than a week of trying, it can all come together and work- no guarantees but it definitely won't work if you just give up.
