Hi Bert,
From what you've posted above, it sounds like something hasn't been installed.
Did you run the BIAB installer and install the PG Music Hi-Q files on your laptop? Also, did you install Sampletank on your laptop?
BIAB needs the Hi-Q sounds in the \dxsettings folder (these are .tgs and .txt files) as well as the files in the IK Multimedia subdirectory (these are .sti, .sth and .stw files)
Regards,
Noel
