can't setup openvpn with t48g

Running 35.80.0.95. Found a great guide on your site for setup, but I am encountering a problem. I go to network / advanced on the web interface, and I see the VPN section at the bottom. I select Browse, and then navigate to the tar file. When I select it, the dialog box box immediately changes to the text "C:\fakepath\openvpn.tar" This is especially bad since I am running Linux. When I press upload, I (very quickly) get a "JavaScript Upload Success!" popup window (with no real indication that anything was actually uploaded). When I try to enable the VPN (by pressing confirm), I get a pop up window that says: "JavaScript Please upload VPN config file first!" I have not been able to figure out what is really going on, and how to get around it.

Thank you in advance
