Everytime I try and record midi on logic it crashes, logic 4.2 , mac os 9.2 Options

[fcwulf]

So I am new to logic. I am using a USB midiman 4x4 and i am connecting midi to logic through oms... mc is os 9.2, logic 4.2 ... so, I get midi running in and out of the track instrument... and I hear stuff through the monitors when I enable audio... but when I go to record midi I get 'There seems to be an internal data loop within OMS' and it crashes ... errrrr
so.. i dont know what to do with that.
anyone know what might be wrong?
Thanks!
