just to clear this topic. Licence check should be done sometimes after update, so it's better to try locus after update before go offline. Anyway then no internet check will be required. Also when for unknown reason there will be some problem and you'll not be able to use Pro version, you'll get after start option to use Pro as Free, so you'll be able to use Locus still but only with some small limits that brings Free version. But I really hope that all will works fine now
