Yes you are right, I tried on another site that never had magebird popup installed and it worked.
The site where it didn't work had an old version of popup installed, I updated it with the one downloaded but it was not taking any License key.
I will need to find where the key is stored in the DB and delete it to make it work perhaps.
Anyway.Thanks for the Module.
