We could not complete your iTunes store request an unknown error occured 50

Question

Yeah. I got this message while I was trying to access the iTunes store and I had to wait about 10 minutes then I got this message. "We could not complete your iTunes store request. An unknown error occurred (-50). "
I am on a multi-user mac mini running OS X 10.5.5 with an intel core on the non-administrator account with most things enabled. I have been having this problem for a while when going from my library to the store. It can't open up the store, but it can download items to my computer from the store still. Can someone please look at this? I really need this issue resolved.

Answer 1

I have the same problem PLUS I get the "Genius is temporarily unable to show you related music..." whenever I select a song. This occurs even when I log in as Administrator. Updating to 8.0.1 did not fix either problem.
I can access the iTunes Store and download music. Genius had no problems uploading my iTunes Library info, and it can create playlists for selected songs. I believe this rules out communications and authorization problems. I have a G4 Mac Mini, a G5 PowerPC, and an Intel iMac with the same problem, so it's unlikely to be a Mac hardware issue. A firewall problem was unlikely (since I can access the iTunes Store), but I tested this with the firewall off. Both problems still remained. Updating Genius, turning Genius off and then on again, reinstalling iTunes 8, updating to 10.5.5, etc. did not work.
The only unusual factor is that I have HughesNet satellite 'broadband.' I cannot see how that would matter, but perhaps the individual song iTunes Store and Genius features don't get along with something in my HughesNet 'modem.' Any ideas from other users?
