Glad you've got it all working camper!

For anyone else who comes across this thread, there are two main ways to install everything into BIAB. You can either download all the RealTrack files and install them (which itself can either be done manually or using the "Master Installer") or you can use the built-in Download Manager which allows you to skip manually downloading and installing the Realtracks.

We have tutorials on both ways of installing Realtracks here:
