Thanks!
It looks like a crash in atio6axx.dll
which is the AMD OpenGL driver
There was someone else who had the same issue, here:

Did you update your graphics driver recently? If so, the person in that thread had to do an uninstall and reinstall of the driver to fix the crashing 
Let me know if this helps
Thanks
