Hmm. Not sure how to solve this one. Tried to install Epocrates from the app catalog. Downloaded fine. Got about 3/4 of the way through the database initialization, and the Pre crashed. So, I restarted it. Now, Epocrates won't load database. So, I deleted it. Then I tried to install again from the app store, but it says it is downloading, yet the progress bar does not move. How to fix this?
