If you're using a laptop, make sure that your function (FN) key isn't on. Most of the newer laptops have a "FN Lock" or "F-Lock" key to toggle it on/off.

Now if you're not using a laptop, your RO folder might have a version of LUA files that's newer than the one currently supported by heRO's client. If you've installed heRO in a folder with any other servers, I recommend you to reinstall it from scratch (you can find a guide here).
