Does anyone know why this would happen, no matter what plane I have loaded? I was using current date, time and season and getting cosistent CTDs about 60 seconds after take off. If I swith to Summer, no problems whatsoever.I've removed all add on scenery and AFCADs (I think) which consisted of nothing more than Fly Tampa's KSEA and still have the problem. What's the deal with this?

Just for future posterity, I finally solved this problem by disabling railroads in Ultimate Terrain USA and UT Canada/Alaska. I found this suggestion late last night in yet another Google search and it's apparently an old problem that was supposed to be resolved 2 or 3 years ago with a patch. I'm running the latest, patched versions of both so, obviously, it still happens on occasion.I'm on my way over there to see how to fix it, or if it can, in actuality, be completely rectified. I have this problem while flying over Bangor, ME too.
