QUEST SPOILERS!

I'm currently doing the ultimate heist quest - this is my first run through of oblivion, so please no spoilers outside this quest! - and i'm at the part where I need to shoot the arrow of extrication into the statue. I stand at the pressure plate, shoot a practice arrow, line it up correctly - and I can't equip the extrication arrow! I've looked at different sites trying to find an answer and have tried unequipping and reeqiupping my weapons, arrows, and even my armor. It just tells me that I can't fire the arrow (it's a 'quest arrow'). Anyone have any ideas? Can I fix this with the console?

Thanks in advance!
