Hi I've been having a problem when I try to log in, it keeps telling me I'm "offline and try agin",

I have uninstalled and reinstalled the game multiple times and nothing works, I know my computer is on line because I've reset the modem twice and checked my speeds and all is good on my end, I'm just wondering if there is a way to fix this problem? I've also tryed droping all my fire walls to see if that would work and nothing.

Thank you,

Brenden
