Unverified E-mail in Desktop Creative Cloud

Recently, a friend of mine logged his creative account in to my computer. However, he never logged out. To make matters worse, the e-mail he is using is not verified (he forgot password, as he uses the address for opening other accounts). Now, I need to log back in to my account, but the desktop app won't allow me to log his account out and log mine in, because of the unverified e-mail issue. Is there any way to log his account out externally, or should I just uninstall de desktop app to reset?
