I thought I had changed my email on dropbox but apparently hadn't. While I was disctracted on the phone I told it to just log in with my google account with my new email and it set up a new account. Now if I log in to change my email it says that my other email is being used. If I delete the new account will that allow me to use the new email? I no longer have access to the old email and I need to get this changed but all my files are associated with the old one.
