Deactivating my laptop from my wife's ADE account

[stuartm519736]

My wife activated my laptop to her ADE account and now I cannot deactivate her account. I confirmed her password and Adobe ID by having her log into Adobe but the same email/password combination does not deactivate her from my laptop's ADE. I tried to uninstall and reinstall ADE but it still defaults to her account. Please how to I resolve this.
