Hi Martin,
The guy that did the winsock fix... Chrome was the only program unable to connect.
Of the two fixes, its the one I'd try first as it looks more like the logical choice.
Seems odd that even a reinstall wouldn't work.
Tell you what... can you uninstall it & re-install it but when you re-install it, right click on the install .exe and choose "Run as Administrator".
Perhaps PGO needs to set something up to get to the internet and unless it has elevated privileges it might not be able to.
Cheers,
Wilson.
