Error - When loading .pit file

I receive the following error on 5 computers at my home, Cannot load file C:\Users\user\Downloads\TS+Desktop_bahakymufrdwtyqwn5uukq55_m.pit

This happens in IE 8, 9, Firefox 4.01 and Chrome 11.0. On 5 different computers. The only thing the same is the router. At work I am able to connect fine into my application Terminal Server Desktops.

Is this a firewall issue, everything seems to point to the firewall at my home, in that it works fine when I connect out and back in through an external WAN address to my V workspace
