I have a gateway laptop running vista. I purchased 251 songs and videos on itunes. When I attempts to download I receives the error. "Unable to check for available downloads. The network connection timed out. Make sure your network settings are correct and your network connection is active, then try again." After running all the useless itunes diags which pass. I contacted Apple and they told him that I needed to modify the network settings. I verified that all network setting where fine. Apple told me it was his computer so I bought a Mac and the error still continue on the new computer. Any help would be awesome!
