Collectible Card Game Headquarters

Hey there, when I try to launch the client and Server nothing happens. Launching Client on it's on just gives a blank text box, while trying to launch Server doesn't do anything at all. I can still launch Xmage via the startMage.bat but would prefer to be able to use the launcher if possible. My Java is up to date and my XMage version is 1.4.28V0.

Help very much appreciated.
