Unknown Error (400) - 8.0.2.20
"We could not complete your iTunes Store request. An unknown error occured (400). Please try again later"
This problem started two days ago. Since then I have tried turing off my firewall and virus scanner, but this did not correct the issue. I then uninstalled iTunes (version 8.0.2.20) and re-installed. The error is still occuring. Could this be a problem in the registry or some preference file that iTunes sets in the background? I am not sure what to do next. Apple Support just recommended that I install the latest version (which I already had). Please help....
