JavaScript Error after choosing storage location

Just trying to get started with channels and am off to a rough start. I get the software installed on MacOS, choose a storage location and am immediately hit with a javascript error. I've tried both Safari and Chrome.16%20PM

Hmm, check my.hdhomerun.com to make sure your firmware is up to date and run a channel scan from there to make sure it finds some channels

I did both of those things.
