you can have more than one, vb will install all its tables with a prefix, libe vb_users vb_settings etc etc, you would have been asked during setup if you want the default, the idea is you can install many instances all with different prefixes get it? and it helps with backups etc

anyway just install your 2nd software using the same db but with a different prefix.. make sure you backup 1st incase it deletes before it installs, but if its any good it would warn you 1st...good luck!
