you got to warp thm properly first mate.

go to the very first beat (open it right up to get it spot on) right click and select set 1.1 here

then move along a few bars and do another. pick a beat then right slick ans warp from here.
i find it easier if you have your metronome on while doing this. (its 2 circles on the top laft)



add warp marklers as many as needed all the way through the track so its spot on with the metronome....sorted.
