iPad and Mac problem.

[HappydaysArehere]

Hope someone can help. Just got my Mac out and looked into “managing your account”on the iTunes site. I saw devices associated with my I’d. I noticed a lap top I had before my Mac. ThoughtI would remove it. To my horror it immediately removed my Mac and one of my iPads. It didn’t ask for any confirmation so no chance of cancelling. I need to get them back as my dh uses the stuff I download from my iPad. I gave him my iPad for that purpose. Then I need my info to go to my Mac, music emails etc. Do hope someone can help. I am not at all good with technology and my Mac is more unfamiliar than my iPad. That is how I got into trouble looking into iTunes. I am an idiot in need of help.
