Well if you have 3.71 m33 the nitePR is different from the other nitePR so wouldnt the 1.50 kerenel not run properlly with the 3.71 m33 nitePR if thats what he has? and yeah The VCS CheatDevice F***s it up so make sure thats not enabled at the same time. so the only other reason would be recent up or down grades right?
