Installing SourceOP DoS Fixer

Hey Guys!
I was playing on a server today and it got dos’d, it was quite annoying.
So I thought I’d put a DoS Blocker on my still-in-development-server.
I downloaded the OrangeBox DoS Fixer from SourceOP, but I cant figure out how to install it. I’ve put the .vdf file in my /orangebox/ folder but my dedi box doesnt load it. plugin_print returns no plugins loaded.

Any instructions please? :slight_smile:

Thx in advance,
Hexo
