Each time I attempt to connect to one of our test database, I get the message "You are not allowed to use PL/SQL Developer on this database" 
My PL/SQL Developer version is 6.0.1.848
I can connect to the same database with the SQL Navigator 4 tool.
I'm consistently getting this error message and don't know what to do to proceed. Do I need to send a request to my DBA? If so, what am I requesting?
Any information will be appreciated.
Thanks!
Paul
