Just done a track in ableton, exported as a wav, went to play it back and the first few seconds sound good and then this massive bit of feedback comes through and echo's on itself into the track until there's none of the track coming though with only this horrible feedback...

track plays perfect within ableton, there is alot of distortion going on but within ableton it plays great...

any help, tips, anything i can do

any help appreciated!! :)
