After i have localized my hero emp_hero_marek in entity/emp/hero_marek and munge, my hero doesn't have a name at all when i play... advise anyone

Is the code name correct? It's emp and not imp? Did you check the Localize box before munging? Did you save in the localization tool after creating and localizing your custom unit's entry? Can you please explain step-by-step what exactly it is you did so that we have a better idea in diagnosing your problem?

The name is emp, after I localized it in the localizing tool I save it and then munge and check the localize box... maybe my localizing tool dont work?
