I have an active personal license. I recently switched my computer and tried installing DT Lite on it. Yet it said that I can't use the license on the new computer. Why is that?
It's possible that your current license reached its total number of maximum activation attempts. You will have to contact the developers of the application. They will provide additional information regarding the validity of the license and its status. Basically, a new serial will be provided to you and then you can install and activate the application again.
