One person having this error was able to give us a crash report containing Exception Code: c0000005 and Exception Offset: 00289ecc; we were able to trace that report to a part of the program that generates textures. So, the problem may be a hardware incompatibility issue with certain graphics boards. If you could tell us what graphics board your PC uses, that might be useful. It would also be good if you could provide a similar crash report showing Exception Offset, etc.; I believe this information is often displayed in the details section of the popup Windows shows when a program crashes. Even better would be a dump file; the first post on the following page describes how to generate one from a crashing Windows application, so if someone wants to give that a try and post/PM me the file, that might be useful.

If you want to try stuff out on your own, updating graphics drivers and so forth is always a good bet too.
Thanks, and sorry for the trouble all.
