Whenever I try to join a server in FTB, as soon as I click "Join Server", I just freeze. The CPU usage goes down to 0.01, and I can just wait there and it does nothing. I am a bit afraid to try anything as I am currently floating above the void in the end. I have tries selecting "Force Update", using various different versions of java, and rebooting to no avail. I think that the problem originated after I used CCleaner and rebooted. I can't find anything good in the log files.
