Hi,
If you start up the game and receive an Authentication Error at the login screen, then you have to get the new Config XML.
You can get the new Config XML files from either of these two links here:
Or
https://anonfiles.com/13p3yfI8of/ConfigOptions_xml
You have to overwrite your old Config XML with the ones linked above (only pick one of the links.)
Hope this helps!
