For the past few days I've been trying to log in to the server but keep getting the aforementioned error. I installed the game correctly, redid it multiple times, made extra sure my details were correct, but still get the same error. I tried remaking my account to see if my account was still there, but it said the name/address were already taken.
I played on the server for a few hours before the update to 7.3.5, and I'm wondering if my account information was lost server-side sometime during that period. Is there anything you folks can do? I really want to try out the server and start building some great Dwarf adventures, but I'm at a loss as to how to fix this.
