VKB Hardware

Can anyone tell me in detail how to assign axes and map buttons with the VKB Gladiator NXT and T-Rudder pedals in FSX? The VKB people insist that it all has to be done with their software, rather than in the game as it is with all other sticks, but if anyone has a VKB stick you know it is unbelievably complicated and the manual is incomprehensible. So if anyone has mastered this could you please let me know how you did it?
