The essential reason for this is due to the basic architecture of DBA and how it uses Pervasive. Or more accurately how it DOESN'T. It is becasue DBA is not set-up as a Relational database but rather a transactional database.
 
I have found that when you were formerly able to do so and suddenly you are not that you can mitigate this degradation by un-installing Pervasive on the server and running the clean utility and doing the same thing on the clients and then re-installing on the server and then on the clients.
 
Also, make sure you are on the latest version of Pervasive.
