I tried to connect again and got the same error. Even after I went into settings and forced close I got the error so I saved the log file for you.

After I restored from Titanium and updated again it worked fine. I'll send you the error log I saved.
According to that debug log the calibre DB was either gone or totally corrupt. CC thought it was there, but it wasn't.

I have seen indications before that something like this can happen. I store the database in CC's private folder on the SD card if there is one, otherwise in main memory. I wonder if there is some situation during an upgrade where that folder is emptied. It seems that is what happened to you.

When I check if the DB is up-to-date I check stored version numbers. I don't check the actual DB file. Clearly I should, and I will add that. EDIT: I *do* check that the file exists. Perhaps I should check if its contents have changed.
