Actually, I kind of killed it.
I was taking it apart..just the little ball thing out and I accidentally knocked the wheel thing out. It has a spiral spring to it...the other glider pads are in place, but one is out ..and of course I can't find a screwdriver small enough to take the back plate off...let alone afford a new one (yes, I realize they're only, like, 10 bucks at Wal-Mart.)
I'm a poor college student..eh, I need to be frugal! Help, please!!!!
