You need to post more details.

What's the nature of the problem?

From a cursory look, it seems like you've completely failed to grasp the basics of following and targetting, which are discussed to death all over this site, feature prominently in the various tutorials, and is made especially clear in Vyn's training video.

If that's the case, then please do us the courtesy of actually using the various resources here (search, wiki, etc) so as not to clog the forums up with duplicate threads.

If that's not the case, and you've got your basic macros set up, unbound your movement keys (as shown in the video), etc, then could you please post more details so we can see what sort of problem you're facing?
