If someone can put up with me for a sec, im not the smartest pc person..
I did option 1 and checked game client.. says english US
Did option 2, changed patch to enUS from SG
But... When I opened c:/programdata/ << blank space
I have nothing in there, no hidden folders or anything.. Did I do something wrong?
What OS are you using mate? if it is windows XP then it is different and is in C:\Documents and Settings\All Users\Application Data\Battle.net\Agent\
If it is windows 7 your using then try just coping this C:\ProgramData\Battle.net\Agent\ and pasting it into your address bar in a windows explorer window, thats the best way to access it.
