I love the look of this cabinet and assembly was fairly simple.  That said, I encountered the same issue with the base board and one of the feet as another user.  As I was screwing in one foot a section of the base ripped off.  Rather than waste all the work I had put into the assembly and deal with waiting for a replacement part I went out and bought a really strong glue to fill in the gaps left by the incident and allow the foot to be secured.  Its been a few days and everything is holding in place well, but be warned that the base of the cabinet is much more fragile and not as well made as it looks.
