Overtime

ah crap, I'm on the wrong forum! I'll ask the guys who built 'playonmac' sry

Hi all, I'm trying to get RA working on my mac. I downloaded and installed playonmac but when I start it up I get the following message. "Playonmac cannot run because of bad language setting on you computer To solve the problem, open a terminal and type: defaults write -g Applelocale en_US " Can someone tell me exactly what this command does, since I don't want to change my default language to US english without a way to go back to UK english. I realise that the way to do that is prob 'en_UK', but still I'd like to be sure. Thanks
