Hey you Guys, thanks for your help!
I managed to figure out the problem, or better to say I solved it without knowing what it was
Anyway, I removed everything and reinstalled each single programme, and voilà, everything works as it should now!
I was so amazed when I became aware about the possibilities, so I send you a bigger than big THANK YOU, PERFECTLY DONE!!!!!!!!!!!!
I´m just wondering what I have to do if I want to use this for IL-2...
