trouble connecting / windows 7

[fastboy21]

hi folks, I could use a little help with my problem:

I can't log in. I get to the login in screen, enter my pw, and then get the "can not connect to the server. check your internet connection..." blah blah.

I am running windows 7-64 bit.
I was previously able to play on this OS, but i had to reinstall windows recently.
I did a complete reinstall of titanium.
I have turned off all fire walls, and done all steps in the setup section (eqhost, etc).
I have tried running all the compatibility modes it allows me to.

do you have any suggestions?

i'm thinking there is some stupid setting in windows7 that i am not turning off/on, but i really can't figure it out. any help would be greatly appreciated.
thanks.
