Loading save abandon carrer
 

Hello gents, I have the following system:

OS:Windows 8.1 x64
GPU:PowerColor AMD HD6870x2 2GB (Dual GPU not Cross)
RAM: 8GB DDR3
CPU: Intel i5 760 @2,8
HDD: SSD Samsung Evo 256, 2TB Toshiba
Silent Hunter 3 Steam version (1.4)

This problem occurred for the first time in GWX mod but it's seem that is happening in vanilla to, when I try to load save game in patrol mode the game is suddenly ending with no reason with "U-boat abandoning mission" mesage. I did have some trouble running this game so I used the compatibility settings Windows XP Patch 3 with administrator mode (my UAC setting is on very low) to prevent the crash from the loading screen but still it doesn't work, what should I do?

Thank you!
