Hyperlite made 2 different jib bases. Yours is the older of the two. They stopped making that base half way through the year. Apearantly it didn't work as well as they thought and had some problems with certain slider surfaces.
Anyway, I've never seen a problem with the old style coming apart, but I would imagine that Hyperlite would be happy to warranty the board for you. I'd be a bit concerned why a dealer that sponsored you couldn't take care of the warranty issues for you.
