I had the same problem, it rubs, shows found keys partially, click on rhe down triangle on upper right and program hangs with not responding message, leave it for a while to see if responds, and get same message even if click on update.
Contacted support@anagicsoftcom , who got back to me reasonably quick ( within 12 hrs and asked for screenshot and the software log; sent them but have not heard back.
fyi xenarmour works well for getting keys and passwords.
