When you Record to the Audio Track, BB creates a separate .wav file that has the exact same name as the songfile but with the different suffix, ".wav" appended.

That file has to be in the same folder as the BB song resides in order for it to be loaded with the songfile.

If, for some reason, it got moved to another folder, that may be the problem here.

You should hit the PLAY button and let the parts generate, ascertain that you hear the Audio file playing with the instruments first, then hit Stop and try Rendering.

Also make sure that you have downloaded and installed the latest update version for your version of band in a box, by visiting the Support pages. Help->About inside BB program will report which version you are running. If there is a later version, download and install the latest one, which will contain all previous updates and fixes as well.
