One user 'SkyHigh' is having issues with the game CTD while entering the flight screen, apparently his high res (widescreen setting) is effecting the game. (1.29 NewMap 26th January 2016) eaw.exe.
However every other version of EAW he is using works with his widend res. He may have an account here, I forgot if he did.

Theres a post over on CombatACE EAW Forum about this....
