There are two versions of Jump Desktop for Mac:
1. The Mac App Store version of Jump Desktop which can be purchased from Apple's Mac App Store. This version of Jump Desktop does not show the trial dialog and does not need to be activated.
2. The trail version of Jump Desktop which can be download from our website. This version of Jump Desktop shows the trial dialog and requires a license file to turn off the dialog. You can purchase the trial license file by visiting our webstore here http://jumpdesktop.com .
If you're seeing the trial license dialog after you've already purchased Jump Desktop it's quite likely that you've purchased the Mac App Store version of Jump Desktop but you're still running the trial version on your machine. To fix this, delete all copies of Jump Desktop from your Mac and then open up the Mac App Store and re-download Jump Desktop.
