I ran into this one glitch in Tunguska that keeps me from playing. I was on the level called "a hard days fight" or something like that. I never finished it and I got off, I knew that I would have to start the mission again. The next time I got on, I talked to Pox and the only options he showed were "recap mission goals"and "leave". It is still like that currently. Here is a list of everything I have tried:
-turning the ps2 off and on
-flying somewhere else and coming back
-doing a side mission and coming back
-starting a side mission and aborting
please can someone help me or tell me somewhere I can email or call for help?

HELP!!!

It looks like your game is broke. Go to your local games dealer and they should be able to fix it. I don't think you will lose any game data by doing it.

Im not sure if thats the case, other files work fine, and I can do everything on the glitched file except start the next story mission.

Exactly. Your game will be glitched only on that mission. As I said before, getting it cleaned will/should solve the problem.
