That was also the Problem with me. Game crashed after 1 Minute.The no refueling animation was enabled.
What do you mean about CPU set to 0?
Just one quick question. If I install it will I have problems with the older GP4 mods? If not then I will install it asap.
EDIT: I just tried it on the standard settings (update 3) without the refueling animation and so far it seems to be working and I don't get CTDs. Hopefully it will work now and no more problems will appear.
The mod looks spectacular! Thanks a lot for the hard work and the help solving the problems
