I'm having an issue with v. 3.4 on my Macbook Pro Retina....click to run it and it immediately crashes. Tried completely uninstalling it (using App Cleaner to get rid of logs and cached files), re-downloaded the latest version and reinstalled. Still same problem...immediate crash as soon as it begins. Doesn't even get to a main window or anything. V 3.4 is fine on my iMac. Both are OSX 10.8.3. Any ideas???
