then how in this world do you even enable it?

You are pretty new. Did you hack your PSP? you know MMS and Pandora? Or do you have a 3000?

And you are supposed to put the mso:/seplugins/nitepr.prx crap (Don't do that one or it might not work I was just guessing as it's been a while since I've had to do it.)

Also BEFORE you update your PSP make sure you backup your crap. You might delete it.
