Im in the room after waking serena up and i see the way to kyrim but there a gate blocking and i cannt find the way to open it. can someone help me please

Im not sure if im bugged or not. im trying to get out of the cave were you woke serena. but there a gate in my way and cannt find control for it. dont how to add a screenshot

You can't go back the way you came, you leave the cave through another exit. Keep searching, it starts from a bridge connected to the middle platform where Serana was held.

i was the other exit. but the stupid chain on the rock was there took a couple reload to get to show up. im good now
