Clojure REPL won't print

[Risord]

I have clean Clojure project created by Leiningen and when I start repl seems to start but enter just makes new lines and it never prints anything. Also these ctrl + , => s etc. keybindings don't have any effect. Any ideas what I am missing or how to debug problem?
