Widescreen Mod HELP for GWX3 please :)

[Tool]

Ok.. I haven't played SH3 with GWX3 in a few years but upon trying to tonight i get the 3d engine error. Here are my specs:

Nvidia 760gtx superclocked
Driver 335.23
24" samsung running at 1920x1200
win7 ultimate 64bit
SH3 1.4 w/ GWX3 edition

I can't get it to stretch to fill my screen. I loaded up the gwx3 widescreen mod in JSGME and i either get the 3d engine error, or if i go and switch my desktop to 1360x768 the game only fills up part of my screen. What am i doing wrong? I did go to load up a saved mission and it crashed, but that may have been due to adding the mod later. Can this run at 1920x1200 or are you stuck with the 1360x768 stretched to fit?

Thanks!
