Game with gold: Tomb Raider glitches at the end

I downloaded Tomb Raider free with the games with gold deal( March 1st/ March 15th 2015) and at 80% it speeded up alot compared to the previous 80%. But i could play, so i did but when i came to( Rescue Sam from Mathias) one of the last mission it
lags/ glitches out.. There are no walls, ceiling or doors. At least not visible. So it leaves me stuck in the near last room, i can look in to the last room but can't enter it. I tried restarting and redownloading it a couple of times, but it didn't work.
Please fix this i enjoyed this game so much and now i can't complete it..

:)

 

Tomb Raider reviews are looking good!

^Well those people are stupid, because Uncharted is Tomb Raider with a little Michael Bay influence. Also Tomb Raider is multiplatform. I'm getting it on PS3.

[/quote]QFT . TR games did come first so who copy who. TBH , at the end every game is copy of another .
