Hi, 

A couple of weeks ago I activated the free plug-in key on my website am now unable to enter the premium key. When I remove the free license key, it tells me that it has been removed successfully although the numbers are still there and it still gives me the option of removing the license key. I am unable to enter in the premium license key or change the text in any way.

I have tried deactivating and uninstalling NBDesigner, however this has not helped.

Cheers,

Andrea
