Not much help, but I have seen something like this happen before, with Microsoft Money 2003 running on XP/Home - loading a certain datafile (which, I assume, had become corrupt) would cause the machine to do an instant soft reset. On Win2k it would blue-screen instead. All other datafiles were fine. Never seen the usually-reliable XP do anything like it.
I never worked out what was happening. I tried opening the same file in Money 2004 (I must have been bored) and that just popped up an error message, so I guess there was some bug in Money '03 that got the OS in such a mix-up that it died in sympathy. It's possible - but a complete guess - that something similar could be happening here. As to where to start, I have no idea. Talk to Serif?
