Ok, I'm also having the same problem.
I have CFW 5.00m33-6 with 1.5kernel
I downloaded Nite PR Rev K for my version and enable it but the bar doesnt show up in my VHS menu.
In my game.txt it says:
ms0:/seplugins/nitePR.prx 1
I dont know if the one is suppose to be there, but no matter how much times i delete it still comes back.
Any ideas?
