Hi, I'm about to re-intall FSX if I cant' fix this problem.Every time I load the game it comes up with a fatal error message regarding FSX.EXE, than it crashes to the desktop. I've done every tweak possible and nothing seems to be working.I really don't want to re-install everything again. My add-ons are: PMDG 747-400X, FSbuild, FSRealtime, FSUIPC4, Ultimate Traffic.I'm using Nvidia 7800 AGP graphic card with the latest drivers on Windows XP sp2 , CPU Pentium 4 2.60GHz , 4GB of RAM , FSX deluxe SP2.Any help would be great, it's getting very frustating.And if you think I should re-intall it all, what are the instalation order.Thanks , Kaue.
