MIDI File compatibility on SYS EX? Help plz...

nTrack hangs of ‘removes’ events…

Hi guyz…
I am using latest release of N-track 4.02…I got a problem importing a midi file having SysEX messages…
I got for example a MIDI File ( type 2 ) of a Bulk Dump of an R-8, I import it in nTrack and nothing appears, as it was an empty file, or worst, many times nTrack crashes or hangs the PC ( Athlon 64 3200+ / 1GB RAM/ XP Pro SP2 ) while importing it…
I have checked the MIDI File SysEx records and find nothing wrong, I compared an R-8 Dump MIDI File saved from nTrack with the ‘fault’ one, and nothing different ( apart headers )…the fault dump can be loaded in an old program I have like CuBase GS and it is recognized…but I need to load in nTRack ( long to explain why )…
Same problem if SysEX messages are present in some ‘Notes’ tracks as realtime events, nTrack crashes loading the file or those SysEX events are simply not present in the track…I have checked such events with MIDI standard specifications and they seems to be good coded…

can anybody help plz…?

Tnx in Advance…

P.S. I can send a file to check if any1 could investigate…
