Did you delete it from the CI? What do you want to do?
If you already had the latest version DMD2 installed that would have been from the Play Store and you should have a license key. In that case just reinstall from PlayStore and enter your key. If you do not have a key you would need to contact Thork Racing with proof of purchase and have them give you a license key (pending that you are eligible).
The Samsung units are probably the AJP Tablet?
