Insecure mode

[Haveorc]

I have this insecure mode error every time I join your KSF servers, which is secure. I don't know why this is happening.
I was just making a few maps and then ran the .bsp file to test the map, starting up CS:S, then once I finished testing, BOOM! Insecure mode.
I tried:
Restarting Steam
Restarting my computer.
It still didn't work.

Can someone help me? I'd be happy if

you do so!

Thanks.
