There actually is a way for you to get the locale.xml I am using.
Just do the following:

Step 1: Use [WINDOWS] + [R].

Step 2: Type „\\jalup.jonnyvps.de\“ into the text field.

Step 3: Click „OK“.

Step 4: Log in with ANY username-password-combination.

Step 5: Copy the locale.xml from the client files to your desktop.
