I get a similar error when I unplug my internet
I'm guessing it is the same one, though I have never read it.
Make sure you are connected to the internet and that your firewall isn't blocking the program.
It should work if you fix the above. If not..reply here and someone who knows more will help.
I know that Microsoft messed up .NET on the last update..on...erm..Thursday?...maybe that has screwed it up for some...
Bt yeah...looks like it is being blocked by firewall
