I used trial fine for the 30 minute demo, ran pirated for about an hour, and then purchased paid.
Deleted cache of google store, services, and drastic, deleted draStic app, rebooted, ran draStic, warned me of license.
Cleared cache again, deleted draStic, rebooted, downloaded draStic from legit store, still gives license error.
Date/time set correctly.
Read some of the topics here ( viewtopic.php?f=7&t=706 )
Error code: 3244
Thanks for any help!
