After downloading The First Templar from steam, I registered as soon as it prompted me to, however, I neglected actually try to browse the campaign or online options once launched. Now 2 days after installation, I launch the game and try to play, but when i reach the title menu, it's saying that my username/password for online play is invalid. So, I go to create one, and now it's saying that my KEY is invalid. What is going on here....
