Thanks everybody for your answers!
I've patched the Game right now and it works...
now I am applying patch by patch and always testing it
@ plj
Hehe i would be hard to learn
Do you know DCS? (Digital Combat Simulator?)
That's also a "real" Simulation just an Flight Simulator...
Have it now 2 years with Hardware for about 1900 EUR and still learning...
(HOTAS Stick, Track IR, some Modules with Switches because a Keyboard hasn't enough keys for that Simulation)
Even WITH Shift,ALT,CTRL etc
