I have read the entire thread. From all of this, I understand the following: 1. The game version must be a licensed copy (I have one). 2. The Tribes of the East expansion must be version 3.1 (I have version 3.0). 3. All downloaded maps and mods must be removed (do I need to remove my own maps?). What am I wrong about, and what did I miss? Do I simply need to register on the Ubisoft website, or is there something else I need to do (e.g., link the game to my account)?
