I'm having a similar issue, the exact error message is:
Fatal Error: Direct3D driver returned an error code (D3DERR_INVALIDCALL) whilst resetting the device
Technical Details: ATI Radeon 5700 series
That is indeed my graphics card, and having checked the minimum required it seems to be fine. And up until the latest past it was working fine, now all of a sudden, poop, won't get past the first loading screen.
Any suggestions beyond the obvious update drivers / direct X? As I've gone through all of that, even installed all the optional updates to my OS, still nothing.
I'm having the same problem: constant crashes to desktop. I did not have these problems before LoR. However, I think my graphics settings might have been reset to max. I just scaled them down and will test again. XFX GTS 250
Not having the exact same problem here about the video crashing, but i am getting and odd thing happening.
Right after the launcher starts to load the game i get a message window pop up saying i need to choose a lower setting to play, card not supported. If i choose the lower resolution settings, the game will load and play fine, but the funny part is that it still loads the game up and runs at the higher resolution settings.....weird

I tried the -dx9 switch but that did not help. My game keeps on crashing and even to the point of locking up my computer. I have yet to do a heat temperature monitor run but other than lowering the graphics quality settings there is not much else I can do in order to play this game. I tried updating the video driver since the old one kept on crashing and only lock up on the second or third crash.
I tried this on LoR on Tribble with no problems but now getting all of these problems. Maybe I missed one or two warning signs now that I really think back.
