It is a crash as in the program disappears without any popup messages. I see no mention of "crashing" in the log. Absent obvious messages like "crashing" I can't make much sense out of the log. So I turn to you to interpret it.
I can tell you that I have no anti-virus programs installed. The server machine has the latest Windows 7 updates. Neither of these machines is used for anything other than media record and playback.
