You CAN'T reqwest default files from FPSC or any TGC product.
Just reinstall FPSC, don't be lazy...
EDIT: Just in case you ask WHY?, Heres the reason:
Uploading default files from any copywrited media is against the law, since you're giving away for free media that it wasn't done by you and you don't have permission by the owner to give it away.
Downlaoding those same files is the same thing, you're downloading copyrighted media for free (and this media is paid, since it's part of a full product).
My love is seperated in 2 parts, 1 of them is 3ds Max 7, the other; FPSC.
