That's why various registers are missing. You have two choices... either upgrade (best and recommended option), or create your own INC files (not recommended for beginners), I have previously discussed their creation and you can search the archives for this at...

It's not a quick job and a lot of hard work (several hours for someone experienced at best)... but at least you have plenty of examples to compare against and help you along.
