MediaMonkey may indicate that you're using the free version of MediaMonkey

even though you've already registered if the following has occurred:

 1. If you've logged is as a different user. 

    MediaMonkey saves configuration settings  on a per user basis, if one

    user registered, this doesn't apply to other users on the machine.

    Re-enter your license information to resolve this.

 2. If the license key was entered but never saved.  

    This can occur with MediaMonkey 2.x as it saves configuration settings 

    when the application closes.  If something interfered with MediaMonkey 

    closing properly, then the settings will not be saved, and the next time 

    you reboot your machine, MediaMonkey will appear to never have been 

    registered. Re-enter your license information to resolve this, and perhaps 

    verify that MediaMonkey is shutting down properly.

 3. If the registry has somehow been corrupted. 

    Re-enter your license information to resolve this.

 4. If your license key is for a previous version of MediaMonkey.

    If your license key is for MediaMonkey 2.x, but you have installed MediaMonkey

    3.x, you'll need to purchase an upgrade to your license key as described here:
