Collectible Card Game Headquarters

I cant update my client throug the launcher. Here's what's coming up:

Downloading XMage from ********************
Failed to download XMage from *******************
Java version installed: 1.7.0_71
Java version available: 1.7.0_71
XMage version installed: 1.3.0.dev2014-11-29v9 (2015-01-17)
XMage version available: 1.3.0.dev2014-11-29v10 (2015-01-23)
New version of XMage available

i replaced the url with ***************** because "Your post looks too spamy for a new user, please remove off-site URLs."

I'm having the same problem. The URL that XMage attempts to pull from throws error 404.

Should work now, I fixed the URL of the launcher definition.
