do you mean a message in the middle of when it's exporting saying "an error occured, the mixdown file will be deleted", if so then i dont personally know what it is but it happens to me all the time, the only way i get around it when it happens is lowering the master volume down quite a bit and then it works, and then i have to just normalize the track in sound forge. dunno if its the same thing you're talkin about but still, this things a cunt. :headbang:
