I just had the exact same error, try launching a different pack, and then going back.

[Zephos14]

I did. Same problem with all the packs. No success whatsoever. I'm back to using the old launcher until this gets fixed.

I am having the same problem. Sometimes though I won't be able to even open the packs to have them download.

First off downgrade Java 7 to Java 6 from here http://support.apple.com/kb/HT5559?viewlocale=en_US. If that does not fix the problem try this go to Finder and on the top left hand corner you should see Go click on it. Near the bottom of the list you should see Go to Folder click on that then type "/Library/Java". In that folder you should see JavaVirtualMachines move or delete it.

I think build 195 fixed this issue, but now my brother cannot even open the launcher, and his Mac has Java 5 I think. Can we make the launcher compatible with Java 5, 6 and 7 or is it only one version at a time?
