Some basic problems

I have installed the game, and it is a solid program. However there are 2 problems I have been experiencing.
1) I have problems with the draft. I can get through the actual draft process seamlessly, but when it comes time to actually play, the system doesn't draw cards for me, but still asks me if I want to mulligan or not. When I say "no", the system reacts as if I have lost, if I say "yes", the system just asks me the same question. This issue doesn't come up in constructed or sealed. Is there any way to resolve this?
2) I downloaded the card images file from the Forge website, but cannot seem to attach the images to the cards. I click "add image" but nothing happens. Is there any other way to attach images?
I use Windows 7 and the latest version of Java.
Thanks for your help in advance.
