I second what Jon (Goodman) said, same thing happened to me,
and when I realized it was the foam, I simply took it out, it's quite easy.
Now talking about the original case, I can tell you I don't like it. It was
designed to keep the camera in the chest, and opening/closing is too
slow for me, as you know it's divided in two parts, you have to unscrew
it from the tripod mount.
So I bought a cheap cube-shaped case and made an adapter for its shape.
It hangs at my waist, where I found it more comfortable, and taking
the camera in and out is pretty straightforward.
Here you have two images, no goodlooking at all, but works for me:
