The RELEASE ABORTED WCN appears only when you release the pickle button too early with the ripple release option chosen and the quantity being set > 1. I.e. when the quantity already released at the moment is less than the quantity to release set in the profile. Wait a bit more until all bombs have been dropped. The release sequence is never stopped by the system in any case, unless the pilot decides to stop it.
Edit
Possible reasons which prevent from the proper release sequence may be:
1) The next bomb can't be dropped because the calculated distance of the current impact point from the previous impact point is always less than the desired one set in the profile. Either lower the impacts spacing in the profile, or pull the stick a little bit while the pickle button is held. The minimum impacts spacing available in the profile is 10 feet. If you want to put all bombs into the same tank, do not use ripples. Just press the pickle button as many times as you need.
2) Your weapon release button is jittering generating multiple "on" and "off" when pressed.
