[Zope] Starting Zope dies with an NT exception

I just copied across a working data.fs from my server to my development notebook, and now when I access localhost:8080, or even localhost:8080/manage, then python.exe dies with an NT exception. I copied the file again a couple of times to make sure it wasn't corrupted, but the same thing happens. And it's still working fine on my server. I also tried reinstalling Zope 2.1.6 on my notebook, but no dice. I presume that there is something about my data.fs that is corrupt, but should it kill python.exe ? Anything I can do to isolate the problem further? -- Regards, Graham Chiu gchiu<at>compkarori.co.nz http://www.compkarori.com/dynamo - The Homebuilt Dynamo http://www.compkarori.com/dbase - The dBase bulletin
