Puffin browser app problems!

I recently downloaded and purchased the puffin browser from the App Store as I'm a tv addict and it was recommended as it's good to use for watching things on. However, upon downloading it I discovered there was an issue with it. A window kept popping up saying "connect to server, portal error, network diagnostics". I then clicked into network diagnostics and went through 3 steps which basically told me everything was okay and to wait a moment and restart the browser again. Which I have done about a billion times and still, no solution. So basically I'm just wondering is there any suggestions or solutions to fix this? Thanks!
