I'm having a problem with the latest GSX updates and Captain Sim 757 III. For some strange reason this is the only aircraft it affects. I will load the aircraft cold and dark then start using checklists and pushback as normal but right before I start the engines I lose ATC and unable to start the engines. I've started the engines just fine without GSX, but the GSX and the 757 are the only aircraft that reacts like this. GSX is fine with every other aircraft except this one. I'm sending the same message to FSDT :-/ also. Any insight is appreciated.
