I don't know if this is your problem, but you can't run two instances of 
the same ZODB unless you use ZEO. (That's my guess, but it depends on 
how you've installed things.) But it's certainly possible. I have at 
least three different versions of Zope and at least a dozen different 
instances on this machine right now.
