Well, the people at Fast Forward (the appropriate abreviation is apparently 'FAF', as FFE is for Far Future Enterprises) are online, and are fairly active on their own message boards.
And in fact, one of their early product was an internet collectible card game (DragonElves, which was the basis for their "Green Races" setting).
Anyway, as mentioned, they did have to pulp a number of their products for d20 STL/OGL violations. So that's some of it. And I don't think much of their other stuff sells very well, yet they've put out a surprisingly large number of products.
When I finally heard about "Sundered Reaches", which is basically d20 on a fantasy version of Mars, I was able to win a copy of it on ebay for $2. List price $25, and it came out this year. I don't think I've ever seen anything drop that much in value so quickly.
Like I said, a combination of poor quality and lack of marketing doesn't generally result in good sales. Which is a shame, as they have a lot of good ideas.
I think most of what they owe money on is free-lancers. Going by what I've read on RPG.net and their own message board

they're late in paying a lot of the free-lancers.
