SoundTaxi removed DRM | Works on one computer but not another!

[RJNJC]

I converted an XMas album with Soundtaxi.
I stored these converted files to a harddrive to which both my laptops (LT1 & LT2) have access to.

I open my MediaMonkey on LT1 and try to burn a CD with these converted songs. No go. I keep getting the DRM error message and so I cannot burn.

I open my MediaMonkey on LT2 and try to burn a CD with the same converted songs. Did everything absolutely fine. Not a problem.

Why this different behavior between laptops, when the files are the same?

Anyone have any ideas??
