This happened to me yesterday as well, but when I reinstalled everything fresh (using the latest releases, not "updating") the issue went away. I've had issues with updating breaking applications in the past, though never this serious, so for the most part I just remove an app and install the latest release instead when there's a major update. Yesterday was a rare exception for me that won't happen again. Developers don't really worry much about creating clean update scripts for beta products.
