I apologize for the multi-post. I contacted support and got a quick response. Thought this was an important bit of information to share:

"Thanks for explaining your problem in such detail. I am very sure this is simply related to memory.
We are aware of memory issues on 32-bit systems and are still looking into solutions. Code is working on optimizing memory as much as possible. Improvements should appear in following updates.
Version 1.0.67 should improve this a bit, but not remove the problem entirely.

Please try lowering the graphics settings and shut down any non-essential programs running in the background.

We apologize for the inconvenience."

While I have 64 bit Windows, my friend does not. This seems to be the issue.
