Need HELP with Minecraft. [SOLVED]

I've recently started playing Minecraft and it's great it's a cracked version tho works fine but i want my friend to come to my world and she can't join me because we both have a cracked version of the game and it wont let us create a server...

Problem being taken care of via TeamViewer.

Problem solved via TeamViewer.
Solution: due to internet restrictions, the Java installer was not able to automatically fetch the necessary files from the Java server. This problem was solved by downloading the Java installer with the necessary files manually, from: http://www.java.com/en/download/manual.jsp

Topic closed, enjoy playing!
