hi all, first off im running os 10.6.8 and using logic pro 9 and an m audio oxygen 49. i dont know what happened but my control surfaces are not working. i have my ox 49 set to the correct preset and still nothing. i know that when it was first hooked up it assigned all the default parameters automatic. ive tried to change them in my control prefs but no luck and it seems very confusing to me. can someone please help or guide me in the right direction. 
thank you so much for your time.
