Ok I messed up my permissions and somehow locked myself out of my computer because it won't start up. This has happened before, in which case I had to use my installation disk and reinstall, but this time it won't even start up with my installation disk. I'm using leopard and when I try to start up it gets to a blue screen with a spinning thing that spins for a while then disappears and shows up spinning again and just keeps on doing that.
PLLEEEEEEASE HELP!!!!
