Concurrent-user site license issues
Access to concurrent user site licenses is based on the IP range you provide for your organization. Access is not allowed if you are not on the network within the provided range.
If you need to update the IP address associated with your account or add an additional IP address, please contact customer support at 800-353-6798 for assistance.
If you have personnel who work remotely, you can assign them an individual login account, however for each individual you create the number of concurrent users you can have access the site diminishes.
