I just had that happen to me. Here is the fix:
Only I didnt pay that much for mine. I got mine for $18. I used it on my BMW E30 restoration project with great results.
Same as above post from Smoke. You take that, drill part of the screw head with the drill side of the bit, then reverse the bit on the drill head, put your drill on reverse and drive the special drill bit head into the hole you just drilled on the screw. THe specila bit head will dig into the hole of the screww and back the screw out. It works like magic and no need to dremel a slot and scar your graphite chassis.
Looks like you need a better hex bit on your driver. Those other screw heads look pretty bad...
