Hello gents I´m new here. 
Yesterday I bought download version of FC2.0, I download it via this torrent and installed it. 
I reboot PC and installed this new patch 1.2.1. 
Another reboot and I used activation key. 
But if I try to start some mission or campaign FC crashes, Windows shows me message like "FC doesn´t work and will be stop" - I can click only for "ok". 
After this, FC starts again but with the same problem - I cant fly.   
In temp folder is nothing - no error message there.   
Can you help me please ?   
Windows 7 64 bit, Intel core i5, 4GB RAM DDR3, NV GTX 470. 
   
Thank you.   
Sorry 4 my english.
