try this worked for me..
- set first DNS to your pc ip
- leave second DNS blank
- turn off firewall (just to check if thats the problem) and all things that use ports.. like skype.. grabit.. msn utorrent to name a few..
- then run FckPSN.exe (ass admin) (0.4, 0.3 might work didn't try) (DON'T RUN ps3dns)
- and sign in
