[mb-users] Correcting a blunder.

I have just entered details for a CD and failed to notice that somehow I 
managed to clear the times for the last 3 tracks.  Is there any 
relatively quick way to correct the blunder?  I tried to update the 
times, but it says there is an associated discID, making editing the 
times impossible (which I understand).  I tried to remove the 
(presumably incorrect) discID but that is now in the normal 2 week cycle.

Suggestions welcome.

Thanks
