The reason your Chessmaster 7000 ( and probably most others ) can't find this in
a reasonable time seems to be that it is simply a very deep combination .

I let Crafty17.10 on a very fast machine run over-night on it and it can't find
it in the first 15 plies but failed high on Ne4 at ply 16 after 424:18 ; I
didn't wait for it to resolve it as I had to do sth else  ( fail-high not
resolved after 558:00 ) .

Someone should try LittleGoliath or Fritz on this :-)
