Serious MIDI sync problem with LE 7.3.1

[Arska]

Problem is:

I've recorded a 3-5 track song and after I've loaded the song few times then all the sudden MIDI sync is gone. The beat jumps around. The interesting thing is that also PT Midi click stumbles along with recorded drums for example. So the whole package stumbles in same manner.

What the heck is going on? This has happen few times and always after I've loaded the previously created file about fifth or sixth time. Somethings happens there automatically? Can some plugins cause this? I have addictive drums and Native instrument plugins in addition to digidesign own plugins.

I have MacBook Pro and Mbox 2 Pro.

I have had that problem too. I could n't figure it out. but every time I record midi, I print it to an audio track. The audio traxks stay in sync most of the time.
