I just updated and I still see the same basic issues...  Just crashes on me :(    
I have gone into settings.... I try update databases..  Gives me Error as expected that I need to login. I click login box.. enter my login...  Hit done... Phone goes back to springboard. 
Reload the app. Go to Settings... Try remove all data... Asks if I am sure... say i'm sure...  And it goes back to springboard.
So for grins... instead of my deckbox login I used my deckbox user ID...   The app crashed, but when I logged back in I had a green box.
I clicked download....  Seems to be working..
So this is a user understanding issue... I was using my deckbox login (my email address)  
What you want to probably say is (Deckbox User ID) The part after the 
http://deckbox.org/users/<YOUR_USER_ID>...  This explains the crashing...  Lost in translation I guess... perhaps if a person enters an email an error box?  No idea... But the app works fine now for me.
