I can't get the loops in Band in a Box to load. What do I do to get them to load?

perhaps i am too late to answer your question and if so just ignore the following:

here are three screen shoots that may be of help to guide you by selecting an instrument track first then selecting a loop to apply to that track from the " loops " drop down menu. I used the piano track for this explanation.

There is also more info/details in the built in manual ( go to the drop down Help in the Band in a Box menu bar ).

Hope that i have not made it more complicated then it really is

I am not attempting to hijack this conversation, but I was looking for a sleigh bell loop in BIAB before Christmas and could never find. Anyone find one?

I don't know if you tried this place, but I've always been amazed at the amount of free sounds they have.

A normal wav file can be made into a loop (although sometimes it takes a bit of editing to get the beginning and end points right), and used in BIAB.

Hopefully this helps (sorry it is too late for Christmas though).

EDIT : I see somebody already edited one for looping on that page I posted.
