Cocos Studio won't start

I’m using Mac OS X Yosemite and cocos studio 2.2.8. Cocos studio crashed on me (it showed me a form asking for my email address to be notified when the problem was fixed) and then shut down. Now I can longer open either the launcher or cocos studio. The icon just bounces up and down on the dock and then disappears.

How can I reset the program so that it works like when I first installed it? Tried reinstalling but still doesn’t work.

Did you tried opening with “ctrl+right button”? Then you choose Open, maybe it can work…

Deleted /Users/kwellman/Library/Application Support/cocos then reinstalled. Seems to work now.
