RoboHelp 10 (TCS4)/TFS in MS Visual Studio 2013 - Unable to Connect RH to TFS

Hello,

I'm trying to connect Adobe Robohelp 10 to a TFS repository using Microsoft VS2013.

I started by following the tutorials linked here, plus the subsequent advice (including registry modification): http://forums.adobe.com/thread/1261856.

(The last piece of advice was to open a ticket with Adobe support. However, after going through the support page, I was directed here, so this is where I'll ask.)

TIA
