Err 99 could mean several different things, such as...
Memory Card
Lens
Lens contacts....
A few things you can try.
Remove the memory card an enable "shooting with out memory card" and see if you still get the error. If it works your memory card is bad.
Try another lens if you can
Clean the lens contacts with a pencil eraser (be careful not to get eraser dust in the camera body or in the lens)
I have heard Canon recommend upgrading the camera's firmware (go to Canon's website to download the latest firmware and follow Canon's instructions for the upgrade).
I saved the worst for last, Err 99 could be related to the shutter failing which would mean a trip to Canon.
Good Luck
