My email address contains a "+" sign. I was able to create my Bohemian account through the ylands website using that email address and receive all emails regarding confirmation and activation. However, when I downloaded the ylands launcher and attempted to login with that same email address and password (which I confirmed worked on the ylands/bohemian site) it would not let me log in. I received an error indicating my email address or password is invalid. I logged into my account via the ylands website, changed my email account to something without a "+" sign and I was then able to login to the launcher with that new email address.
