Hello.I just started playing the game,finished the tutorial so I wanted to do a real match but after it started the game blocked and I got the "Don't Send" problem.
I entered the game again but now it gives me the error after 5 seconds.Is there anything I could do to make it work?
I searched for an identical thread but i didn't found any.

What os are you using?

Also did you try reinstalling?

I am using Microsoft Windows Xp Professional and yes I reinstalled it but it still dosen't work!
I can do the tutorial but that's all!If i try anything else I receive the error.

Try using one of the Betas see if it still is buggy.

It might be just 3.86.

I managed to solve the problem
I have to disable the anti-virus before I enter the game.It works even if i reactivate it afterwards.Thank you!

If you don't want to constantly disable your AV software look in it's config for how to set exceptions - then just add Toribash to the list.
