I can't play an album I bought on iTunes last night because it says my id is wrong

A few months ago I changed my apple id email. I purchased a few albums last night and when I tried to play one of them, it says my computer isn't authorized to play it. Instead, it just plays random songs. I tried authorizing it with my new and old emails and passwords, but neither of them work. I tried what I found online, but that doesn't work. I don't know what to do to get the album to play.
