Why doesn't the Sighthound software see the license I just purchased?

You must log into the Sighthound application with the same user ID and password you use for the Sighthound account you used to buy the license. Otherwise the desktop application doesn't know you purchased a license. To fix, go to Help -> Show License Information in the application, right click on the dog logo and select 'Disconnect my account'. Close the program and log back in using your Sighthound account credentials.
