Segmentation Fault

I have always had the hardest time getting FastDL to work. And now I am trying again. Here is the portion of the server.cfg that you need to see:

"sv_downloadurl"        ""
"sv_kickerrornum"	"0"

"sv_allowupload"        1
"sv_allowdownload"      1

I don’t get what’s happening here that is causing it to not work, but it doesn’t download anything for anything that I have on my server.

P.S. I accidently made the title segmentation fault.

Does anyone know what is wrong here?
