Hi Wendy ...... there is a bug in the latest version of RB.
The previous version of RB was quick at loading and generating .MGU and .SGU BIAB songs ....now it takes forever.

I am waiting for the next update to BIAB and RB ... not holding my breath though !

I think this problem was addressed earlier this year or late last year .... but it has now come back to haunt us.
