Thanks mate, will try this now.Make sure when you open iTunes your phone is set up properly - I.E. Should not show the Welcome page.
Once you're past the Welcome page, on the left hand side of iTunes right click your iPhone and press backup, make sure it fully backups.
Download the cinject_0.4.3 again, off chance you may have downloaded it corruptly.
Quit iTunes, unplug your iPhone, hold down the home button and power button until you see the apple logo, let go of it, when it's back on go into settings > General> Password Lock and make SURE you have no password lock on your phone.
Once you have done that, replug your iPhone and try again.
Summary,

Try CMD all over again.
Tell me how that goes.
You've been a massive help, much appreciated.
