hmmm.... not they are showing. had no filters.  it literally said 0 cards, 0 decks. I logged off and back on and then it suddenly showed back up. weird. I'm relieved though!

Hello,
  I logged in today to find my complete database missing.  It says I have 0 cards, 0 decks. What happened?!?!?!?  I spent a LOT of time and effort adding all these cards and I don't want to start all over.  Can this be fixed?!?! anyone?!?!?!?
