Update hung up?

[Clak]

So I tried to manually update my NC with the 1.2 update. It rebooted and as far as I know began updating, but now it seems to be hung up. It's stuck on what I assume is download mode, exclamation point inside triangle with little android beside it. Anyone else have this happen? I want to restart it but I'm afraid it didn't finish the update.

edit- Heh, oops. Forgot about clockwork mod being there.
