Cannot log on to Sony games..Follow

Im having a serious problem logging on to anything that has to do with Sony. I cannot log on to EQ2, EQ1, and i also cant connect with station.com it has been like this for a week or more i dont understand whats going on . Ive tried Virus scanning, spybots, rollingback, defragmenting, and cleaning up hardrive none have worked. Please let me know what is going on .
thank you
Sam
