drum packs moving files

i bought the six drum packs and installed them no problem, but when i tried to put the tracks i wanted into a separate “gig” folder on bb manager it said that drum loop was missing on all the tracks?.. i really want to be able to put songs in set list order, any ideas??

Sounds like you have my have accidently created a song part with no loop, you will need to delete this before you can continue.
