Hey everyone. I'm having trouble with authorization. All of my purchases continually require authorization. When I type in my password it says that my computer is already authorized and is the one of 5 computers that have been authorized. But it still continually asks every time I try to play a song, therefore rendering my songs unplayable. I have de-authorized all computers and this computer and tried again. I've been through all the steps in the knowledge base help article for these symptoms without success. I then tried to upgrade my purchased items to be DRM free but some wouldn't, even though on the store it says they're available to iTunes plus. It even says some aren't available on the Australian store, but that is what I used to purchase them in the first place. Anyone have a solution for this? Thanks.
