Not sure I would recommend a V2 to anyone. First, you would might need to deal with the registration code and second, it is a 7 year old hub at this point with no thread (but it is still supported at this point). Plus the other nasty possibilities that could pop up… did the seller remove it from their account and have they updated the hub within the past few years. Just my opinion 
Work with ST support to resolve your issue. I posted a link above so there may or may not be a possible resolution (may or may not be the same issue) so hopefully @nayelyz can offer assistance during the week.
