I waited for about 2 hours for the mods to start working, and when I get to the "marketplace" (Don't know what to call it) I was only able to download one mod before I kept on getting barraged to sign in again and again. Please help! EDIT: Got it working literally immediately after I made this thread, lol.
People are downloading mods at an alarming rate so the servers are a bad and not working well. I'm waiting for the servers to cool down.
