I was having the EXACT same crashes when i installed Project Blue mod. Many people on this forum tried to help me, but it didn't end. Well, but i have done it myself. Today when i realized that other users are having the same issue too, i decided to share the simple trick ..
Step 1: Browse to your FPSC Installation Folder
Step 2: Run FPSCreatorCleaner.exe
Step 3: Press Y
Step 4: Wait...
Step 5: Press ENTER
Step 6: Repeat Step 1 to Step 5 until you get "0 files"
FPSCreatorCleaner.exe come with FPS Creator, many of us never noticed it and a few other tools such as CountPolygons.exe.
