Collectible Card Game Headquarters

it hasnt been really working for a while, occaionally shutting off while iw as in the middle of a game, now it just wont even start up at all, please help

Restart your PC, download latest launcher from xmage.de, place to new folder and run it. If can't then go to java.com, install java and run launcher -- it will download and install all other files.

i tried both of those things and they still dont work
