Hey guys, I'm new to forum posting in general.
I just discovered after reading IndyColtsFan84's post, what it is there is a file called act.dat, that contain my activation which i backed up prior to upgrading my HDD. I was bedazzled by the fact that my purchase games wouldnt work after format. It said that I needed to go onto PSN to activate. Anyhow, what i did was upload that act.dat file to home/exdata/act.dat .
hope that helps if no one else has tried that.
I got my previous paid games working again. Now to try all that other stuff you guys been talking.
