Well...I read all the responses and thanks alot. I reinstalled the game and it still messes up. For some that didn't understand, I meant that when I type something, the text doesn't show up, not the whole box, sorry .
Here:
-The text doesn't show up for me, or for anybody else, me and my friend tested it. Plus I flooded a server with emptiness and nobody seemed to respond.
-It's not the servers flow because I went on like 10 different empty servers and it still didn't work.
-I'm fresh out of ideas.
This is all In-Game, the MTA client chatbox works fine.

Thanks for the help.
