[Wine] problem with wine and Lord of the Rings Online

[cosmo18]

I am having a problem with Lord of the Rings Online. The games load up  but after a few minutes the game video locks up but the sound can still be heard and I can not seem to fix it. Here is the error message I get  http://pastebin.com/LGDpeV4q I am running wine 1.3.21  on mint 11 64 bit KDE, compositing is off, graphics driver is nvidia 270.41.06, and 32 bit opengl drivers are installed. Does anyone know how to fix this?
