Cookie 4 on El Captain

Hi,

I purchased Cookie 4.5.4 on the App store 01/25/16. Been using it on OSX 10.11.3 for a month and 2 days ago I noticed the icon disapeared (menu bar). Cookies has stopped working.

I tried to open it from the finder but nothing. I uninstalled it completely with appcleaner. I redownloaded it from the app store and rebooted my computer, still nothing. It has died on me completely.

I really don't know what to do with this. Is Cookie 5 the only way to go from now on. I'm really confused.
