PSP-PS3 Remote play..

Okay I already have an account setup for the PS Network. Updated the PS3 with the latest version via Internet. But when I try to logged my psp with the PS network for remote play it says "Please update." So I went to the psp network update to get the latest version, I got a message saying that it was the latest... WTF!!

What do I need to do? I have a psp slim 5.00-m33 cfw

It is not the newest firmware on your PSP- Just the newest m33.
You'd need to update to the newest official firmware which I do not advise.
Maybe there's a work-around.

I hope someone knows how.

Interesting, I could use remote play via Private Network (not via Internet). ahhhh does this mean that I have to buy a a New psp? Well the psp-GO is out.. might as well huh? Any advice?
