Collectible Card Game Headquarters

I was trying to copy a new deck in from text and the program was slowing down a lot so i exited it. After I relaunced the program, when I click on deck editor it slows down dramatically and then the page loads and its just the dark blue background. I updated Java, updated forge and it is still happening.

Hi,

there are two buttons in preferences (at the top of the prefs list) to either reset battelfield or deck editor layouts.

That should do the trick.
