I am afraid that I have to correct my earlier response. By having a clean start and going through the cycle of 2D, VC, Locked Spot it did NOT solve my problem. I have eliminated the addons where I set CPU priority and made sure no other add-ons were running but still a CTD about 1/2 through my flight. I am at a loss. I will also go back and deinstall things like DBS FollowMe and see if that is having an effect. I was flying the current C-130E. I do have base pack 1 & 2 installed as well. If I find anything I will post it here.
