Collectible Card Game Headquarters

I have been trying to get the new masterbase working but to no avail so I decided to delete magic workstation and re download to see if that will fix it, however it did not and deleted all my decks that I spent a long time refining. Is there any way I can get there back? Never had a problem like this since I started playing on here 4 years ago.

Whew nevermind managed to get them back, but I still can't figure out how to get the updated data base...

I have the same problem> I think its the gamepack!
