"Check for available download" "itunes store unavailable"

Similar problem started just the past few days. Try to buy an App and get "Accessing iTunes Store" then an error message We could not complete your iTunes Store Request. The network connection timed out"

Make sure your network settings are corret and your network connection is active, then try again.

I know the network connection is fine as I just updates OS X 10.6 with today's 2 updates. No problem searching the store... Only downloading does not work. Tried all suggestions on Apple site and no luck.

I'm seeing the same thing for several days. Trying to download some movies and tv shows I purchased, but have been unavailable.

I know exactly what happened. You had an old download in your queue that wasn't fully downloaded that became unavailable. This same thing happened to me (no problem if i let things fully download in one sitting--just couldn't check for available downloads) and the apple techs could give me no answers for a very long time. Finally, one tech went in and analyzed all my purchased items and found I had some freebie tv show in my queue that I'd never allowed to fully download. It was no longer available and was causing an error. The program was removed from my queue and everything I'd lost for weeks immediately started downloading from the point I'd lost it. Write to iTunes help and SPECIFICALLY ASK them to check this, explaining that you've done everything else possible to try to fix it.
