When you install your license, you should have received the message

200 OK

from the server. Most people get this message without any problem, but then discover that the system is still displaying invalid details.

What you need to do is re-start the CensorNet proxy. From the web interface, navigate to the Overview page (System->Overview) and then click the button next to Filtering Proxy (even if it is green already).

Select OK when asked if you really mean to do this.

After a few moments, the proxy will restart, and you should notice that the expiry date and user numbers are those from your new license.
