I am not presented with a screen where I can enter my user number and access code.

There may be several reasons for this. 1) You have entered the web address into a search engine (e.g. Google). Unfortunately, that will not work: because your data are handled confidentially, CBS uses a secure server. To access this server, enter the link directly into the address bar of your browser. 2) You have missed out the ‘s’ after ‘http’ when entering the web address. 3) You may be experiencing a technical problem. Try another website and see if it works. If not, your network connection may be at fault.
