Invite partner link doesn't work - reroutes to teamviewer.com main page

I have a user that I am using the Invite Partner via e-mail option.  Everytime she clicks on the

http://connect.teamviewer.com/v12    link, she gets rerouted to the teamviewer.com main page.  I tried clearing her cache and cookies in her web browser.  I actually tried both Internet Explorer and Chrome and the same thing happens.  I tried the same procedure with someone else attached to the same network router and her link worked perfectly.

Is there some setting that I'm missing.  I really need to remote into this persons system so any help would be appreciated.  Thanks!!
