Windows 8.1 updated to Windows 10 and problems with Drafsight

Hello

I'm user of DrafSight 2015 x 64 (spanish) and Win 8.1. I was working over an old set of plans scanned long time ago (some are BMP and most JPG) wich I'm redrawing using them a a reference picture in a layer  and making new drawings in a different layer.

Today I upgraded my Win 8.1 to Win 10, and my reference pictures became  just a white and gray rectangular shape.  Tried to re-import pictures in a new blank document and the problem still the same. Any ideas, some help?

Thanks!
