Pocket IE and "unable to resolve url" error

My Jornada 820 can access the internet via ICS thanks to Nick Charlton. What a patient guy!
But getting to the forums at HPC Factor gives me the error "unable to resolve url" when I click on, say, "Handheld PC Professional" to get to those threads. Nothing loads even though connection remains solid.
I've searched the forum, but perhaps used search phrases which didn't hit?
any suggestions? Thanks.
