Cant chat.

I cant send out any chat in game. Pressing T opens my chat bar but when i press enter it just stays there. This has been happening for a while and ive tried a few ‘fixes’ with no avail including

verify local content
disconnecting joystick
deleting all rust files and reinstalling
trying to disable and re-enable chat via console (was told to try but the command given was invalid)

Anyone got anymore ideas? I use a steelseries keyboard/mouse win 7 i5. gtx 970. duno if you need anymore info
