Can someone shed some insight on this error. I downloaded a Korean version of the app (after I've been using the English version), it change my entire interface language, I uninstalled it, now my English version is acting up. I get this prompt at the top of my interface, when I type in the command "setcvar('language.2', 'en') I receive this error. Again any help appreciated cause I am stuck and I really enjoy the addon.

Thanks
