MagicCustom doesn't open?

Odd thing:
Im trying out Deckbuilder / MagicCustom / My2k for the first time.
I installed deckbuilder correctly, switched everything just fine but whenever I attempt to open Magic Custom just, nothing happens. I noticed this before I downloaded deckbuilder as well. In an attempt to solve this I downloaded a fresh copy of mok's, updated all the art, updates, etc. and tried again- same problem.
Any thoughts?
