I'm guessing you have a recent version of BIAB. If so...

When I run BIAB loop, the background is black with white chords.

Try running "Options | Return to factory settings | Return to MOST factory settings". This will return settings to their defaults.

Before you run the above, though, it might pay to save your present settings. This is also available under the "Options" menu.
