Hello everyone 
So since 1.4 i experience a persistent crash when launching FS (via launchpad of course 
as soon as the screen goes black loading the game, it crashes with an similar report as shown in the first post....the RendDX9.dll report^^
Note: BF2142 (no FSmod) still works fine!
Searching around in this forum i found several solutions describing similar or identical (RendDX9.dll) problems..none solved the prob so far, unfortunately the most promising solution is not clearly described.
The "start /affinity 1" solution(?) found in this thread (respectively also in these: this and this (german)
....but since i start FS only via launchpad i dont know where to add the command or how to create a .bat file for this...or whatever i have to do to play FS againnnnnnnn... 
Please give me a super-noob newby the beginner lvl1 description xD
Of course i tried out alle usual approaches: updating vista, video drivers and dx, reinstalling fs 1.4 (full) checking for .bak, reverting launcher and data to v1000, starting via Admin, using XP compability mode etc etc
Then i assinged the bf2142.exe with the tool "CPUcontrol" to a single core (which should have the same effect as the command i guess)....no change, still crash
This makes me doubt about the core solution in general now but i can say then, i tried everything from my side and i welcome any help 8)
Apart from all this....until 1.4 i already enjoyed FS a lot, my big thanks and respect for the devs
