From the look in the pic, I see what you're saying. the corner statue (the thing that holds the crystal) is completely missing. Just a flat pedestal left. From the pic, I'd say the game didn't load the interactive pedestal correctly.

I'd caulk this up to a graphics glitch. If you've reloaded the game (shut it down completely and rebooted your computer) and the statue is still missing after that, try looking up your graphics card from the maker and seeing if there is a new driver out for it. I've seen a glitch like that in other games where the GPU driver was the culprit. Also, check to ensure you didn't update drivers and have two running at once. Driver conflicts can also cause this issue.

I'd also try mousing over the area where the statue should be. Even though it isn't visible, the game may still recognize that it's there. Though the interactive point may be ~extremely~ small due to the lost image.

EDIT: I'm thinking a "top down" look may work best on this. With the statue not loading, the cursor may be "looking" past where the interactive point is. By looking straight down on the flat pedestal, you may be able to click the trigger point.

Q: Have you played this install of the game past this point before?

If not, this may also be a corrupted install. Search for ways to save your game in another folder, and a re-install may also help. I know this can be done, but I'm not sure what files to move to where. I do believe this has been discussed on this forum elsewhere though.

Best of luck.
