My NitroSell PAM installation has changed from Professional Edition to Lite Edition. How do I restore it back to Professional Edition?
First off, you need to verify that your database is properly synchronized. To do so, close PAM, synchronize (possibly twice) using NSc Sync, then re-open PAM. PAM Professional Edition should now be displayed.
If PAM Professional Edition still doesn’t open, ensure that the database name (in PAM, under Options > Configure Database) is the same as that displayed in NSc Sync (on the main Configuration dialog). Re-configure your database settings as necessary, then re-synchronize.
One final check you can perform is to make sure your computer is set to the correct date and time. You can learn how to set your PC’s clock here: http://windows.microsoft.com/en-ie/windows/set-clock#1TC=windows-7
In particular, it’s useful to ‘Synchronize with an Internet time server’ to ensure you always have the correct date and time.
