Gamespot.com or cheatcc.com , I use those as alternatives if gamefaqs doesn't help. If both of those don't work then I try the walkthroughs on youtube.com and finally if none of those work then I try googling it. And if all those don't work then I usually post about it on gamefaqs.com. Have you posted your question there?
Hope I helped ^^
Edit: Whoa!! You must really need this lolz, you responded within the minute he responded o.O Anyway, I should have fully read it instead of just skimming it. It looks as if you have a glitch or something, happened to me in Okami (cutscene wouldn't happen) and the Assassins Creed: Bloodlines (Guy wouldn't die o.O). The only way I got passed this was shutting off the game then restarting it. Maybe it's a bad rip o.o If it's a retail, then idkays XP
