tracktion 3 slow playback

[nipturner]

Hey people

Ive been using tracktion 3 for years now and today I was recording midi and when I finished my drum track and played it back it was playing back very slow.
I restarted tracktion a number of times and it didnt change the problm. I also went into another track and the playback was fine. Its just that one edit and its really pissing me off coz now im thinking ive gotta re-record the drums for this track which I dont wanna do.
Any ansewers???
Cheers
