Sometimes (and I stress somtimes) there is a language issue with the software.

What I mean is if you are running the Japanese language version of Winodws, a program configured for an English version of Windows can have issues. I have seen this happen usually with keyboard mappings and programs not configured for different character sets.

That being said, Stanley is most likely right and it's your RAM. Your scene might be too big / complicated and Bryce is attempting to reach for resources which are just not available.
