[Lost Lydia during Thieves Guild questline. How do I retrace my steps to find her?]

Sometimes if you haven't had too many saves, I just go and reload an earlier dame

 

[Graybeards]

Hi, I have a problem with a shout quest from the Graybeards. They sent me to

Silverdrift Lair. Now, I've already finished the original quest here, don't remember what it was. Anyway, now I can't get past the puzzle. The gates are closed and it's not taken the tiles. I know because I have them in me book? Any help?
