I keep getting the message to 'merge or replace' openng iTunes.

For some reason i have two accounts in iTunes. I do not use the me.com account and do not know when/why it was set up. Only 8 apps in it and I do not care about them. When I open iTunes with my phone plugged in it says I have 2 accounts - merge or replace? Apple says never to do either! Also, they say that they cannot delete the me.com account!!!!!!!!!!!!!! This happened a year ago and a tech fixed the issue. I have now talked to 2 SR techs and they do not know what to do. Have any of you had this issue?

Windows 7 IE10 iTunes latest version - probably the problem! BUT - they have uninstalled/reinstalled.

Thanks, CJ Green
