Server addon not working???

Well a friend and I were going to add a fine system for our DarkRp server and I added restarted the server and it doesnt work.
Do I have to add to FastDL or Did I install it wrong?
I extracted it and p[ut it [in the addons folder like it said .
Any help would be appreciated.

Thanks,
