Hello Rico:
My guess is that your installation on your new computer is out of sync with that of your database from your old computer.
When you start BD on your old computer, what version does it say that it is? Do the same on your new computer.
My guess is that your old computer reports v3.0.2 while your new computer is somewhat less than that (e.g. 3.0.0 or 3.0.1).
In that case, the solution is to upgrade your new computer to v3.0.2. This free upgrade is available at the bottom of the Product Info > Upgrading from v2.x or 3.0 page on this web site.
Let me know on all of this please,
Jeff |
