Drums midi file from Nuendo not playing stylus in sonar

Lots of oddities, here. First, all the tracks start at Measure 25, so you won't hear anything until you get there. Then there's just a single note in each track of the new files to establish the start of the clips, and nothing else happens for another 16 measures or so, while the drums in the original file start right at 25:01:000.

The "Original" file sounds like it is pretty much mapped to GM drums. The "Stylus" file is actually 5 separate tracks, the last of which is called Stylus RMX, and seems like it's pretty much the same track, except it starts 3 measures and one beat too early, so the down beat kicks are on the last quarter of every measure... or something like that. I kind of lost track in the process of trying to align things.

I could go on, but basically the new file's a mess, and needs to be straightened out by the individual who knows what he was trying to accomplish.
