I am having the same problem as users Svend and Gil above. When I enter the registration key for Sketch Drawer 5.1, it says the “key is valid and can be activated now”. But when I click on the the register button, I get an “Activation error – the license key has been already activated” and the program stays in trial mode with no ability to save anything. Bummer!
Since this has happened to more than one of us, it would be nice if the software developers could help us get this “valid key” working so we can test out this software to see if it’s worth purchasing.
A little help, please!
