Update to my review: I uninstalled the app then reinstalled. Still no connection, still get the server error. I even downgraded to version 4.2.2 that I had on my computer and still had the server connection failure.
Like many others, I now get a server error after the 4.3 update. Weblock automatically disables itself. Critical error, devs. Heres hoping you push a fix immediately.
