Collectible Card Game Headquarters

Small problem: When I try to select a server from the drop-down menu, I get a bunch of what I assume to be java code.

Question 1: is there a way to fix this, or do I have to input the server name and port number to connect to a server?

Question 2: Is there a list of functional Xmage servers who support EDH or have EDH communities?

I enjoy using localhost to goldfish and build decks and see if they have any mechanical problems (do I have enough mana/ draw/ removal/ etc), but I want to test out my newfangled EDH decks against others.

Go to Preferences->Connection->URL server list
Check that the URL is exactly this:
http://XMage.de/files/server-list.txt

Probably you have still the old no longer valid XMage.info instead of the correct XMage.de URL.
