My GamerSupps Blue is clumping, is there anything I can do and does GamerSupps give replacements?

I bought GamerSupps Blue late last year and I've used less than half of it, and it's already clumping. I've heard someone say that the Blue is old and that apparently GamerSupps don't make it anymore, is that true? Is there anything I can get back from GamerSupps for this disappointing experience?
