Remote Desktop License Issue: your session will be disconnected in 60 minutes.

After I installed the RDP Licensing Roles and Features, activated the license, and did the configuration, I get this message. I have been trying to do the configuration and following the instructions that I can find on the internet, but it seems not to work for me. I also notice it doesn't recognize the User Cals I installed. Do anyone of you encountered this error? Thanks in advance.
