LE-101, LE-104, Code of Conduct - Cant play in group and cant post my name in Chat

Hi,

having a couple of problems:

  1. If im trying to write my name (GordonFreeman) in Chat it says (only the name or in a sentence):

Your message has been detected as containing content which does not adhere to our Code of Conduct and has not been sent to chat.

  1. If im trying to invite people in a group or they try to invite me in a group im always getting Error LE-101 or they dont see my invite and im getting LE-104. Tried it with different people on the same Server (EU West).
