Re: iTunes authorization: " ... when I try to authorize the computer or make a purchase it just says not
completed and try again. I changed the password but that didn’t help."
Seems you must have an Account if you were able to change the password/
You may want to try re-starting your computer, before you try again.
If you haven't already seen it: Wondering whether Appl support's online article (link below) can help:
Authorize a PC to play iTunes purchases - Apple Support
Eg: says:
"You can authorise up to five computers (PC, Mac, or both) at a time.
To play a purchased item on a sixth computer, you need to de-authorise
another one. An iPhone, iPad, iPod or Apple TV doesn’t count as a computer.
- Go to the iTunes app
on your PC. - Choose Account > Authorisations > Authorise This Computer, then enter your Apple ID password to confirm (if requested)"
