We had a similar error on our Maximizer server. We could finally solve it by adding manually the necessary ODBC drivers and editing the registry.
Before you go ahead, be very careful, since you could render your system instable or unusable editing the registry.
Check your ODBC settings (as Admin)
In the system DSN section you should find the entries DefaultDB and MAP_YourAddressBookName.
If they are not present or incomplete, you need to create them.
Using a workstation with a working system and comparing the entries we were able to create the correct DSN entry. If you don't have a working system to compare it with, then you would be better off with a complete re-installation.
If you do, you can try to create the same DSN entries as in your working system.
However, we were not able to set up the DefaultDB entry. If your DefaultDB entry is missing too, then you could copy/paste the registry key from your working system to the faulty one:
HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBC.INI\DefaultDB
Then you need to change the Driver path which you find in this registry key to the correct location.
I hope this helps.
