Hi Hector,

Check for a CLOSE ALL or CLOSE DATABASE code inside your application. You can use the Tools->Code References tool to search it.

Also, if you haven't already, put your setup codes in a Session class and set the DataSession = 2 (Private). This will help prevent it from being closed outside of the object with the USE command.
