Java being outdated or otherwise first comes to mind. But without knowing operating system (+ 32bit, 64bit) and java version (+ 32bit, 64bit) not much I can suggest without wildly giving you methods to "fixing" a problem. The launcher log might also shed some light on the issue, and with this posting a launcher log may help.

 

Edit: Just realized these instructions would fail since you're having issues with the cog icon anyway XD, if you're on windows itll be in %AppData%.techniclogs (by default) and on Mac it should be in ~library.technic .... or something, not 100% sure (someone on mac able to indicate its path please?)

I updated the post to answer your questions

You're running Java 8u20, see http://www.technicpack.net/article/view/concurrentmodificationexception-in-java-18020.89

 

I'm assuming this is breaking some other aspects of the launcher as well (for one reason or another on your system) - as per the article states, downgrade to Java 8u11 or Java 7u67 (Recommended on this one, personally)

You are using Java 8_20 and are experiencing the error which is discussed in the top post on Technic's front page: http://www.technicpack.net/article/view/concurrentmodificationexception-in-java-18020.89
