All of the links and options within I-tunes are working except when i try to purchse a song or album. I am having no problems navigating within the store, but when clicking on the "buy" link to purchase a song or album, there is no response from I-tunes/ nothng happens. I have an active I-tunes account and have downloaded tons of music over the last several years. I have never had a "non-response" from the "buy" link.
Any help or suggestions?
