Lately, I've been getting a message that my computer is not authorized to play some (well, the majority) of my music because it is "not authorized." I then get the message to authorize my computer, which I do, but I get another message that my computer is already authorized. This is where I am stumped. I deauthorized all the computers connected to the account, but no luck. Has anyone else experienced this problem? Any fixes? Any help would be great. Thanks.
