Inability to connect to any of the servers of the list could mean that the game detects that you're using a pirated copy of the game, and thus prevents you from connecting. This would be very similar to the way Battle.net works with pirated copies of Starcraft.

What sort of error do you get when you try to connect?

Do you use Steam?

And Valve Verification errors sounds a lot like what I mentioned in my previous post about pirated copies. =\
