Pro Tools LE Midi Track Sync Problems

[JustWannaBeAbleToJamAndNotEmbarassMyself]

I'm having troubles playing back Midi Tracks on Pro Tools LE 6.4, on
Windows XP. The drum track is not staying in sync with the other
tracks.

Here's what I've done. I downloaded a midi file off the net, and
imported the midi file into Pro Tools LE.

I then create a New Aux Track, and add Battery's demo Drum Package as
an insert. I then assign the output of the midi drum track to the
newly created Battery Aux track. So far so good.

Start Playing everything and after a short while, the Battery drums
get farther and farther off, from the other tracks.

What could be causing this?

One more thing I should mention that might help diagnose the problem
is that I'm using an MBox connected to my Dell Latitude laptop via
USB.

I'm listening to the output of Pro Tools through the headphone jack on
the front of the MBox.

sounds like your record buffer is set too high...should be under the
setup menu then hardware...lower the value to about 256 if you
computer is fast enough to handle it.
