Unable to upload or download models.

[NHMatt]

I asked this first in the bugs section without much luck. I have uploaded and downloaded models on the same program and same computer for a while. Now I am unable to connect when clicking on either the upload, download or G buttons. It says "unable to connect, check internet settings". I checked everything and nothing has changed, I went into the firewall settings and added SU for allowed programs and still no luck. Thanks for any help.
