Each named FotoWeb user can access the server on a maximum of 10 devices. Each device is registered with a special token when the user logs in to FotoWeb from a device for the first time. If users spend all their access tokens, they cannot log in on the 11th device.

Should this situation arise, the FotoWeb server administrator can manually reset all the user's device tokens. This is done by logging on to FotoWeb as a user with user administration privileges and accessing the User Management console. (Tools menu - Manage Users/Groups) 

Open the properties view for the user in question and select Log out of all sessions to clear the user's sessions and allow them to log in from a new device.
