hmm I did not instal your mentioned versions, some of your links were dead, I took the latest ones. because I was not able to find all old versions. And once I did it, server have issues like i written before, than I took version L4toolz from Spirit_12, because we have almost the same errors.
I established Local server and joined to them, but I am worry about that my 5th friend will not be able to join.
@ spirit_12: I have worries about Unknown command "sv_removehumanlimit".
Do you think that I sould reinstal all addons or whole game ?
