The problem is...
I played CS2D and this never happened to me.
My Firewall and Anti-virus doesn't block anything (I've set all).
Few weeks later (I didn't play some days...) I opened CounterStrike2D.exe.
Still

But, when I tried to join a server it appeared this...
"Binary Code Modified! Do NOT modify CS2D!"
Now...

I don't have any cheat program and I didn't modify it!
I download CS2D again, I replaced all the .EXEs and still same problem! But is only when I join a server!
When I create, no error...
Even redownloading...
What the f*ck*ng hell is going wrong?

I don't want to loose my sprites, cores...
BTW: a core.edc error happened. I downloaded it again, but that problem was solved...
Now this binary sh*t.....
