Poptropica Cryptid Island Puerto Rico glitch?

I'm playing poptropic right now, and I've done everything and proven every crpytid real except chupacabra an yeti. And I can't get past Puerto Ric part two. It doens't give me the option to drive the jeep and it has pilot's there that one won't talk. Then there's a guy that you can chat with like in the chat rooms and has the option to battle but can't. And when I talk to someone they say "Char1" "Char2" or "Char3" depends who I talk to. What do I do??
