Game Crashing After screen flashes black

[osamazellama]

Hey guys, newbie here, but I was just wondering what might be causing this error? I can load the game perfectly fine (excpet for the insane amount of lag of the main menu) and get into the a mission fine, but when I get into the mission as a pilot, my game freezes for a few seconds and the screen goes black then goes back to the game and plays for a about 10 seconds perfectly, then another black screen. This happens about 5 - 6 times then it crashes and comes up with the error:- m_pd3ddevice- reset(&m_d3dpp) d3derr_notavailable, and then after that d3derr_invalidcall.

I'm running the game on lowest graphics and 1900 x 1080 res (or something like that) without vsync, though I originally had vsync on but that didn't solve it at all.

 

System specs:

Windows 8.1 pro

Geforce GT 635M (driver version 344.75)

Intel® core i7-3630QM CPU @ 2.40GHz

16gb RAM

Also this is a laptop (All I could afford at that moment, wanted a gaming desktop so badly)

 

I really want to play this game because I love flight simulators, especially WW2 ones, so any help would be greatly appreciated. Thank you :D
