Special Request <3

Please do NOT remove the name arctium from the final binary. Blizzard filters their crash logs based on localhost and the string arctium in the binary name.

NOTE FOR SERVER CONNECTIONS

A valid certificate matching your authentication/bnet server host name. That certificate needs to be loaded by the authentication/bnet server too
