AMPPS 3.1 doesn't start in OS X Yosemite 10.10.3. I had an old AMPPS which I removed. I uninstalled the old app (and restarted just to work on a clean environment). I installed the 3.1 version but when launching, the app icon is endless bumping in OS X dock without staring. Only the "Force Quit" is available, indicating that the app is stuck.
