Resident Evil Outbreak Problem

[Necron]

I'm playing the level 'Hellfire' on Resident Evil Outbreak, and i've just got to the bit where you place the RED JEWEL in the statue bust. But, when I click 'Use' on the RED JEWEL when standing in front of the statue, nothing happens. I have tried moving slightly to see if I wasn't in the right place to place the JEWEL in, but still nothing works. Does anyone know why it won't go in the statue?

Just in case it's important, I'm playing with Cindy and Yoko and Alyssa are my team mates. I've been in every room except the one which you go through AFTER insterting the RED JEWEL. (I've been on this level a loooong time). I doubt this is important, but, my virus gauge is at 78% (eesh), and I've already tried saving it in the Security office (the room where the statue is), and reloading the game. Still no success.

Any help would be much appreciated.
