I KILLED THE JAGUARS, BUT THE GAMES HANGS UP. I CAN'T GO ANYWHERE. 

If it is the boss fight where Lara gets mauled on the back, after the fight should be cutscene of her skinning it, and should be a campfire/bridge you and Jonah both have to lower.

If by hanging up you mean freezing/can't move, maybe exiting the game and restarting?

I can't recall what part of Peruvian Jungle map the fight was :l

Just a guess, but there is a prompt afterwards to heal. Have you done that? Even if Lara seems fine, that may be what's preventing you from progressing.

I'm in the area of the first jaguar fight. I've killed 1 jaguar, the other ran off. I can't do anything until I heal, but I apparently don't have any health to heal with. F1 does nothing, and the "Tap 1 to heal" prompt stays on screen. Since Lara is holding her side, she can't climb out. It would be a real shame to abandon the game after 30min of playing time, just because I didn't save before this. Argh! 

I'm playing on a New Game+, so I'm full up of everything available in the pit area.

Sounds pretty desperate. I was thinking a jump top a base camp but I'm uncertain if that's even possible.

A saved game from Stella's site might be a last resort. Maybe someone else here will have a better solution..
