Can't get passed a certain part in Arkham Asylum?

[95BlackGA]

I'm try to 'Locate the warden using his DNA trail', but when I go into the "abandoned tunnel", I get no option for a grapple to get over the gate. Is there something I am suppose to do, or am I just screwed?

apparantly thats a restriction on pirated game copies...

if you have a legit game, then try a reinstall and make sure its done properly....
if it isnt legit....then theres no way around it....

Yeah, I saved my gamesaves, and reinstalled. Got passed it finally. After about an hour of playin' around with the game I decided to just reinstall.
