Unless your crank is the top-of-the-line (read expensive) XTR, it requiires a V-2 Octalink and, yes, V-2 and V-1 octalinks are incompatible. The V-2 has longer and wider splines so a V-2 crank will not go onto a V-1 bb far enough. If you have a V-2 crank on a V-1 bottom bracket, that certainly could explain your problem. Look here for a description and pictures of the two types:
