After pushing out beta 13, we discovered a problem with the file scanner that prevents files from being scanned into the internal database. The problem was very minor, but it occur in a pivotal point of the backup process, so we releasing beta 14 as a quick fix for the bug. This problem prevents the scanning process from completing, but otherwise has no effect on your files or data.
Beta 14 is now being pushed out on automatic self-update and should reach your computer presently.
