Hello Carol,
I certainly recommend upgrading as I do not know if V3.0 runs on Vista - or how well.
However, in your case, I bet the problem is that you were running v3.0.2 on your old system and all you did was to install v3.0.0 on Vista. If that is the case, then logon to this website, and get the upgrade to 3.0.2 from the Product Info >> Upgrading from v2.x or 3.0 page - at the bottom.
The way to know for sure is to take a look at the program version versus the database version in the splash screen that displays when you first start BD. If you are running program version 3.0.0, then upgrading to 3.0.2 will probably allow you to use your old database.
Let me know either way please,
Jeff |
