Script error

When I join a server there is a warning sign in the top left telling me there are script errors. When someone talks on the mic, all I hear is very loud static. Also, when I move my mouse, my character in the game flips out and turns around in multiple directions very crazily. How can I fix this problem? I did notice there are a ton of red lines of text in my console command screen. Any help would be appreciated.
