Trouble with Barbossa

[lizatagious]

Don't laugh at my noobness, please. I don't care about these forums other than to get help so if my sig isn't as cool as yours, please forgive me for my lack of internet savvy.

I'm only level 2 and I'm on the Barbossa quest; whenever I sail to Devil's Anvil to get the pistol (which I got after the first attempt; I have it in my arsenal before I even set sail in Port Royal) and I go inside to practice on the monkey, I can't leave. Barbossa ceases to talk to me and when I try to leave, my pirate either starts floating in a myriad of vague blackness that reflects the sky (with no distinguishable beach) or runs on it for miles and miles and miles. No ocean, no sand, no nothing. I've restarted the game countless times and the same stuff has always happened. Is this normal? Is there something I have to do, or is this a legitimate bug?

Thanks in advance for the help.

Edit: Okay, it's not that hard to give a simple 'sorry, I can't help you' or a 'what make is your computer?' I'm flattered you asked--I have a MacBook OSX, I think. The game downloaded just fine and there's a bit of lag but other than that, everything's good. Seriously. I found out from somebody else that he's supposed to start telling you about the pirate code. How the hell do I get him to start? Anyone, please?
