Unable to load mission after installing first patch

[ROXunreal]

The patch has screwed up my game. Made the menus much more buggy, I cannot go "back" once I click something on the menu, clicking the back button doesn't work, pressing esc doesn't work...

But more importantly, I cannot play any mission, it won't load, but will give me the following error:

Method not found: 'Int32 maddox.sound.WGroup.getHandle()'

I really hope a solution for this is found soon. I could play the game before the patch, with horrible performance on my not so good system, but I could at least dogfight over water at about 20 fps. Now I can't even load the mission

Same here. Since the patch, the sim is freezing on the mission loading splash screen.

SimHQ forums report very little change after patch install still stutter and little to no FPS increase over land, epilepsy filter removed but still no SLI support despite Luthiers statement that the filter was killing SLI.

I have a improvement over land for sure, on a GTX280.

before i could only play over the sea, but now i can fly over the land 30fps+ over 3000ft.

before it was in the teens.

roll on buying a 560ti.

Same problem here, the missions loads to 95-97% and no go!!

Same problem - Anyone found a way to fix it and get missions to load?
