Cricket Championship lets you choose between two interfaces: basic and advanced. There are very few differences between these two interfaces. When you use the 'basic' interface you will not be presented with as many tactical options for playing matches. With the 'advanced' interface the full set of tactical options is available.
All you need to do to change the interface you are currently using is go to the Set Preferences page linked from the left-hand menu on the Account pages and make the change. You can also change the interface from the page to pick your team and the page to set your tactics.
