Wow, what a bummer.
GAL
is one of my favorite scripts (maybe even my favorite), and it's so hard to find coders who support what they sell.
I realize, of course, that you probably never made a lot of money off your products, and perhaps that's what's driving the lack of response.
Perhaps you could raise the price to make it more appealing? I myself would be willing to pay more.
At any rate, I hope things go well with your family and your bricks-and -mortar business.
