Great app! I saw that you had a new version, I downloaded it, but when signing in the Facebook authorization page, I got an error message: “An error occurred” and when I clicked the 'okay' button, it took me to the 'success' page, but stuck there until I clicked cancel and the program crashed. I uninstalled, deleted the folders listed on the first page of this thread, rebooted, reinstalled, and tried again. I got the same errors. The last version was working fine, so I don't know what happened. Any ideas on how to fix?

Edit: Solved! See the discussion on the next page, and my step by step solution on the next page of this thread.
