Welcome, and thank you for being a My Best Buy member! Updating your email address can definitely help prevent you from missing any important emails or notices of sales. Updating your email address alone shouldn't impact your purchase history though, so it's quite odd you're having such difficulties. I suspect you may have instead created a new BestBuy.com account with a new My Best Buy membership, rather than simply updating your email address.
I'll be delighted to dig further into this though to see exactly what happened, so please keep an eye on your inbox for my private message. You may check your messages by signing into the forum then clicking the envelope icon in the top right corner of the page.
