Firstly, you turn off capslock by pressing the little 'capslock' button on the left side of your keyboard.
Then you read the first post of this thread.
Then if you have any trouble, you read the rest of the thread. If you still don't know what to do you post a more specific post here asking for help.
And please, please, please don't make a post to say 'I can't get onto the dream omg why/ omg omg!!!!!111'
