Not a nice reply Winston. I don't claim to be very good with computers or the like and thought I would get some helpful advice by posting my problem. Why did i change my ID? Because I wanted my current email address being used not the one from a previous long forgotten past and rightly assumed that I could CHANGE my ID the same way one can change a password within modem tech and maintain the account. SO SORRY I acted so dumb in your eyes Winston.
I haven't suggested you are dumb, indeed I only think people are dumb if they don't ask about things they don't understand.
I was asking why you changed your Apple ID to see if you really needed to, it sounds as though you may not have needed to.
You can change your personal email you use with your Apple ID, but you can't change your iCloud address. If you do this you can continue to use your old Apple ID and without causing problems with purchased content.
