For some reason I am unable to access the itunes store. When I try, the progress bar stops at 50% and nothing happens. I have uninstalled and reinstalled itunes, and someone suggested I de-authorize and re-authorize the machine, but still no joy. I am running Windows 7 32-bit, with PC Tools Spyware Doctor and Windows firewall enabled. I used to be able to access the store with no issues, and I cannot correlate this issue to any new hardware or software installed. Any help would be greatly appreciated.
