I had the same experience as other users here so there HAS to be something wrong. I had prior versions of Sketch Drawer, I installed the new program and got the license activation error. I uninstalled the prior version and re-installed the new version and I get the SAME message. Now I have an unregistered program. What to do? Obviously this is a real problem because so many people have been complaining about it. This is a GREAT program and I’d love to get it fully working again.
