Tryed to update my card database but it gives me a message about not being able to unzip update file.
I believe that means there isn't an update. You should be up to date.
That's right. Unless you are experiencing troubles with the database, you shouldn't have to update it. The most recent database would have been included with the installation.
Correct. I'll try to make the message less cryptic in the next version.
I can't find the graveborn deck in the expansion section. Also when I go to the expansion section section and try to add a premium deck to my precious it adds one of each card from the deck to my precious. It doesn't add the entire deck. Now I don't care if it doesn't add the basic lands but it would be nice if it added the correct amounts of cards from the deck to my precious.
It does what it says on the tin.
