I installed Windows 7 Professional 32 bit using the upgrade option. Since installation, I cannot access the internet with IE 8 nor can I access the iTunes store (making using my iPhone very difficult). I can access the internet with Firefox and also with Outlook. I have tried turning off my antivirus, I have also tried reconfiguring the Firewall and even tried turning it off. Nothing worked for either of these programs. I am extremely frustrated because certainly IE8 should be able to access the internet, especially as they are both Microsoft programs and should be compatible. ITunes 9 is also listed as being compatible. Any ideas.
