XTR Crank Falling Off - HELP!!

[Ssushi]

I just built a bike for the first time and have the new style XTR crank set.

The left crank just keeps on coming loose. I can't understand why. I tighen the 8mm allen bolt in the centre and install the left hand thread nut (which seems to contribute nothing - that I can see).

What am I doing wrong?

Please help - I'm desperate to ride this new bike!!!

Cheers

Do i tighten the adjusting ring against the crank or against the bottom bracket? Currently tightened against the cranbk - I think this is the problem...
