Ages ago I found the same kind of problem wit AOL. I changed e-mail & tried to switch to a different engine. Switching wasn't a problem but wiping out AOL was difficult. It was entrenched in my computer & hidden in the nooks & crannies. I don't know how we got rid of it but I kept deleting AOL in the properties every time I came accross it. Good luck with the new e-mail.
We just got a notice that our Verizon will be switched over to something else & that will have new addresses, What a pain for someone like me who they say they'll walk me through the process. Will they come to the house to do it cause it won't be just a walk in the park for the likes of me. They're telling me to do things that I don't even know what the words mean or refere to. Pains.
