Your existing AOL account corresponds to the iTunes database as account # 8675309.

Here, read this.If you can't figure it out, since you paid for support, ask them to find your dchrist24 AOL and convert it for you.
When that happens, it's like #8675309 now is accessed via
dchrist24@gmail.com, for example.
It may help if you login to the AOL account and look for an old e-mail receipt to give them the MXC______ receipt #.
You have two accounts. I can't explain how correct Taskiss is...
Also, you can be charged for downloading the same
song twice, but App Store/iBookstore are more forgiving, and as long as you sign in with #8675309, whatever the account ID changes to, when it checks Purchase History and finds MXC______ with Angry Birds, you don't get charged.
If you go Store > View my Account... and look through your purchase history, there's stuff you bought which isn't there on the @yahoo, right?
Get access to your old AOL account resolved, authorize with whatever it turns into, and accept that you played a part in this by making two accounts.
