This is going to sound like a stupid question...but, since it had me going around in circles for an hour before I noticed it...I'll ask any ways. Did you attempt to connect to nexus, from Vortex and through FF, AND authorize the connection? When you boot up vortex and tell it to connect to nexus, it will bring up the browser you have defaulted and connect...the nexus message on the main page changes and asks if you want to allow it (it looks, otherwise, normal). On my screen (laptop 17") it didn't look like anything had changed and FF was being retarded or, Vortex was not communicating, until I panned down looking for a FAQ link, then I saw the authorization request. Once I told the nexus page, through FF, 'yes' or, 'allow', or whatever it was...everything started working fine with Vortex.
