If you don't already have a free registered account, you'll need to set one up in order to gain the free access. This is very straightforward and doesn't involve you having to provide any financial details. You need only to register your name and email address, and you'll then be sent a username and password. That's it.
The free access weekend runs from today until 23:59 GMT on Sunday 25 February.
