I accidentaly deactivated a user in the Management console which removed her. I cannot add her again by clicking "Add User" as it tells me the email address is already added. If sher tries to follow the link "https://login.teamviewer.com/cmd/joincompany" she is asked to login but when she attempts this it states that her account has been deactivated and she should contact the comapny admin (me).
How can I reactivate her?
