Itunes store???

Ok, everytime I try to get into my itunes store it tells me that I should check my network connection and try again. I'm connected to the internet because I'm able to use it on Internet Exploror and AIM. I tried restarting my computer and reinstalling Itunes, neither worked. Any suggestions?|||This sounds like it might be a firewall issue. Open up your firwall software and see if i tunes is blocked.
