How do I get out? I've done it before. But it won't let me go up this thing where you first meet your friends, and there is a fork in the road. Once I told them where to go, I went to go level up my materia, but then I went all the way down, but I didn't go to the Jenova figth thing. Instead, I went back up to train some more to defeat the Weapons, and once I was done, I went back to the place where there is a fork in the road, and it won't let me go back up. Can someone help me with this problem?
