I'm just starting Validation. VALDREV won't run on either of our computers because it expects a floppy drive and we don't have one. Our desktop has four card readers, and although VALDREV finds them all it says they're all invalid. The laptop has a CD drive only, but VALDREV says it has found more than one drive. It doesn't show any found drives, though, and won't run. Has anyone else had this problem? What do I do, please?
