So are you running Biab bb folder on the laptop and have the RealTracks and Drums folders on the flash drive ?
or is Biab bb folder on the flash drive also ?
are you using the wav files or the wma files on the laptop ?
If you use the wma files on the laptop and freeze the SGU it should load the wav files on the Audiophile Edition computer.

You can use Fast Copy to select the RT RD folders you want to copy and filter out *.wav so it only copies the wma files.
