Starcraft 2 error: "download authentication module error"

[Le^stat]

Had this error when trying login the first time.


Here is the fix....

Your cache folder should be in one of these locations, depending on your operating system:

For Windows 2000 and XP, it can be found at C:\Documents and Settings\%username%\Local Settings\Application Data\Blizzard Entertainment\Battle.net

For Windows Vista and 7, it can be found at C:\Users\%username%\AppData\Local\Blizzard Entertainment\Battle.net

I just created the cache folder... Win7.
