Well, if according to Sony you're not one... then it appears it's back to sorting how you're able to get IN.
As scary as it sounds, would it be possible to re-read the initial Tutorial here and retrace your steps... to see if something was left out and/or if it's SAVE file related as wicked insanity proposed earlier?
I am speaking with CJPC now who is going to relay this to one of the resident PS3 Devs in a bit... hopefully we can finally go through it all and get to the bottom of the mystery.
If I had to take a wild guess, I'd say it has to be savedata-related assuming rda990 is on PS3 FW 2.20 like everyone else trying.
I am trying downloading the home beta file the old way downloading it in place of a store demo see if that has any magical effect in theory tho its effects would be the same.
umm does this ps3 proxy thing work with windows vista because I dont think its running properly it goes to the box that tells me to do the proxy thing on my ps3 then says press ok after I done but after that nothing happens and I cant connect to internet on my ps3 when I do that. Can som1 confirm if they are using vista and it works?
