out of range error

[Nightrise]

Hi,
iv been playing the outfront version of men of war for quite some time now, but recently got a new PC. after installing outfront on the new machine i played one game which worked fine.
Sometime after i changed my desktop resolution, and now when i try and launch MoW i get past the intro adverts but then get a message on my monitor saying 'out of range', i have tried various resolutions since this but i keep getting the same message.
Any help would be much appreciated.
