Yes, I had same thing happen. There is some notice buried in their not-so-clear help page that says there is some problem with Adobe Air. I ended up deleting tweetdeck and using seesmic as a substiture but now that no longer works. I posted a question here asking if anyone can recommend a working replacement.
