The pack looks great but here's my issue...I think you'll have much better success marketing these packs to the general FPSC user if you package them in a format that is ready-to-use in FPSC. In other words, the majority of users don't want to spend $17 and hours upon hours finding tutorials on the forum on how to get these things to work in FPSC and then hours trying to change/convert files and FPE/FPI scripts.
Just my 2cents on the subject. I'd buy your pack right now if it was ready to go for FPSC with no more work from me than simply downloading and running an installer.
