NAV 2016 - NAV Content Pack - Won't Install

Hello I have a NAV 2016 environment that I wanted to run the NAV Content Pack for.

When I try to get this Content pack using the instructions in the link: 

https://powerbi.microsoft.com/en-us/documentation/powerbi-content-pack-microsoft-dynamics-nav/

I get to step 5 (i type in my OData URL which I know is working, my windows username and password that has admin rights in NAV) and click sign in, and the loading circle just hangs. I've waited overnight and still it just sits there.

I read some things about having a personal gateway so i tried to install it but the installation failed could this be related). Now i don't see that step in the official link provided. Is this what is preventing me from accessing my NAV data?

I really need to get access to this NAV Content as the client is expecting it.

Any help would be appreciated.

Thanks,

Dan
