Trying to re-login to Spectrum, getting "encountered exception 'Uncaught' (5:5)"

I recently upgraded my channel package from spectrum. The channel refresh wasn't showing new channels so I was going to try and delete the source and re-add it. Now I'm getting an error after entering my credentials,

Rebooted the Mac running the DVR program, checked for updates, still getting the same issue.
