You will need to go to the folder where the database is stored on your computer (location is dependent on Mac or Windows system) and either delete two folders or rename them.
I am on a windows 7 computer so your file locations may be a bit different than mine especially if you are on a mac.
Close the manager. {this requires right clicking on the manager's icon in the taskbar} (Clicking the X in the upper right hand corner does not shut down the program, it only hides it)
In windows Explorer go to the following folder location: C:\Users\{Name goes here}\AppData\Local\Adobe
Find the folders -
AAMUpdater
OOBE
Rename them
AAMUpdater.old
OOBE.old
Start the manager, type in your username and password then OK the license agreement.
At this point you should be ready to go.
