Collectible Card Game Headquarters

I just installed the new version of xmage today and now cannot connect to my local server sense it is the wrong build. My version 1.4.42V5 Server version 1.4.42V4 is there a way to fix this? I allready forced the update, and s reinstall didn't fix the issue.

It's running app while update. Try to restart machine or close all java.exe apps by task manager. After that you can install again by update button.
