Crash to desktop GAUGES\PMDG 777 X.DLL

Hi all,

i've just landed to RJAA after a long trip between las vegas and tokyo.

However during the descent phase i've got a cdt after tried bypass a holding point @ pixus from melon and to runway 16R.

On the fmc i've got a restriction altitude above 6000 @ melon, after 4000 @ pixus with the holding point after pixus @ 4000 and direct to the runway. 

So when i selected pixus and past instead of the holding point FSX froze and crash to desktop with the info below in the title.

I've reload fsx 3x and tried the same thing and fsx crashed 3x...

What do you think about that?

Thanks

FRED
