This error is caused by incorrect configuration settings in the Advantage Database Server. Take the following steps to correct this issue:
1. From the server, click on Start, Programs, Advantage Database Server, and open the ADS Configuration Utility. 2. Click on the Configuration Utility tab which will open to the Database Settings tab. 3. Change the number of Work Areas to 250 times the number of users on your user license. For example, if you have purchased a 10 user license, then the number of Work Areas will be 2500. 4. Before clicking 'Apply', ensure all users have closed out of Medisoft. Click on Apply and Exit. This will restart the Advantage Database Service and apply the updated Work Areas.
