Sim Crashes to Desktop after loading into Start Screen

[Andrew_LaFon]

I saved a flight to reinstall ORBX FTX Vector, Base, and North America. When I tried loading back in after I installed the BASE Pack it said scenery.cfg not found, I then installed North America and it didn't say anything so I proceeded as normal but it crashed when It got to the menu where you select your aircraft and everything. I've tried reloading maybe 10 times and nothing has worked. Anyone know a fix to this?
