I don't know how I could lose it. All I know is I converted from MYM to QuickBooks in 1996. I have gone through about 8 to 10 computers and have moved my household 4 times since giving up on MYM. I recently discovered an accounting need to go back to 1988 financial data and voila, I can't find my MYM program discs. Miraculously. I've got the data discs though.
My big problem is it looks like just about everyone else has lost them too. That why I'm asking for help to find them.
I saw Version 6 on Amazon, but it was the book only without the software. I would take copies as long as they worked.
