I'll be able to tell you what to do, I've completed the game too many times. 
I'm not sure where you are though. What has happened recently?
I think D21 is right, you're at the part where you have to go down the elevator and blow a hole in the wall with C4. I was stuck on this part when I was 8 or 9.
