"Cannot find or open file" error drag-drop audio from Drumcore

I can drag & drop the midi loops from Drumcore (as a plug-in) but not the audio loops.  Get the "Cannot find or open file" error.

If I recall correctly, I used to not have this problem.  But did recently do a Windows Update to my DAW rig which included an update to XP SP3, so maybe thats related.

Would appreciate any suggestions...

Thanks
