Using the one from the link you posted in post #18 Nimloth. I will try the one you quoted tomorrow, thanks.
EDIT: Turns out the culprit was FlashFXP, it was saying it was overwriting the old 27.cer even though it didnt exist as I had already backed it up, changed to SmartFTP and after that worked no prob, thanks for the reply Nimloth, cheers.
I decided to test this out today to see if it still works and it did. I was too afraid to stay on long so I immediately signed out. Well, I tried again a bit later so that I could sync my trophies but now I can't log in anymore. I get an error code: 80710A06 "You have been signed out of Playstation Network." Any Ideas?
I can still sign into my main account with my OFW 4.25 PS3.
I manged to get back online. My dilemma is, the only reason I wanted to get online was to get my act.dat back, I went into playstation store, downloaded a demo, and still nothing. I checked to see if my exdata foler had a newly found act.dat file, to no avail. I thought all I needed to do was just log into PSN to retrieve my long lost act.dat? Any help will be greatly appreciated.
