Nope, he's well past that. I'm pretty sure Hadvar has gone down a hallway before the player and triggered rocks to fall which would usually be behind you. He says "guess we can't go that way again" or somesuch. Any lollygagging on the player's part might find these rocks coming down before you get a chance to pass under them.

Ok, yeah. Loads of answers. I'll do as suggested and start over a third time. I'll just reinstall the game as well before i do to exclude some possible issues.
Thank you all for trying to help :]

tcl!

no need to start over.

I agree.

If you are on the PC, open the console (tilde key ~) and type tcl and hit enter. Close the console.
Then move through the rocks to the other side. Type tcl again (to turn it off) and follow the guy to the exit.

I ponder if this is a bug in 1.6 and nobody has noticed..

Here is a game play video of the first part of the game. Watch it, study it, let it become you, young one.

you are gliched all to oblivion, those rocks should not be there yet

No i just started a new character and i dont have the problem

it might still be, not everyone experience the same bugs

It happened to me twice. Might be i ended up somewhere else from loading the game, as it really looks like i've been past that area looking at the map.

Yeah, thanks for the console thingy, but i wont use it :] If i first learn how to, there is no stopping me and i' end up ruining my own gameplay, haha.
