Replying to Full Tilt Question

The middle buckle on my BB pro's doesnt loosen anymore, no matter how hard I push the little tab, nothing happens. Am I fucked? Should I shell out 30 fucking dollars for a new one + installation fees? Im gettign new boots next year anyway, so I'd like to spend zero dollars and make these work, but its as tight as it goes right now, and I cant ride it like that, so something has to happen before I can ride em. If I can get them to slide in the little track and loosen I'll just keep it at the same setting for the rest of teh season, problem is, it doesn't do that at all, even after repeated attempts. Fuck.
