Why won't my Droid 2 update apps?

Hi! I went into the market this morning and saw 11 updates available. I hooked up to my WiFi and had at it. One at a time the updates failed (after apparently pulling down the entire app update – 16 MB for Angry Birds), but then the “un-updated” app showed as updated in the market. I know the updates didn’t take place (no St. Patty’s day levels on Angry Birds Seasons!).

I went into the application manager, cleared my app data and rebooted the phone (recommended previously and usually works). Still no good. Any idea what is going on?
