Thanks catymag, It's working!! - partially. I get notification "key code accepted" but still, map shows demo notification in background. After I exit and restart ozi, I get registration window again..but strange - I ignore it, enter teh program and there is still my license info stored in program app under "help", but again, "demo" notification in map background. How does that affect functionality I didn't notice yet, because I'm new in OziExplorer app..
