Hi, my whammy bar on my custom S won't stay in. So I screwed it in the day I got it, then I got it out again using the little hex key it came with. But now that in trying to put it back in, it won't stay in. When I looked inside the small hole the key is supposed to go in to, it doesn't have the same connection point anymore that was there before so now when I put the hex key in there, it doesn't do anything. Did something break or fall out or something? Thanks
