Can't upgrade license to C9

Same Here! Cant do anything because it zapped my license for 8.5 and says I have nothing to upgrade and continues to fail connecting to server for maintenance. Probably 40 or 50 tries over several hours now. Confident it will work eventually but disappointed that there is not more licensing server capacity and don’t quite understand why it zaps the license for prior version before it is able to license the new version. That’s just bizarre right?
