BWP BG1+TotSC issues

I installed the BG1 and the Tales of the Sword Coast, Now though, the BWP installer says I'm missing:


data\MPGUI.bif
data\ExArMaps.bif
data\ExPAreas.bif

I can't find these anywhere, and It seems to happen each time I install it. Can anyone suggest something? Or would someone possibly have these files that I could either download from or get these emailed?
