Now it gets a little further. I checked the registry and can see that indeed my older application had left some 5.1 registry entries there. Now however, it goes through all the xcase/tables ok, and gets a << Files SDT.VCX does not exist. Method DBCXMGR.INSTANTIATEMANAGER.>>

After that, if I bring up my DBC in Stonfield Database Explorer, it starts spitting out all kinds of error message.
