Every time I try to log in to Beyluxe Messenger it writes: "Invalid username and/or password". I am sure the name and password are right.
Maybe, you've pressed wrong letters or numbers and if you have another account, you're probably using your other pass. So try all the passwords if it still doesn't work, make a new one. Hope this works.
If you know the login details are correct, it's possible that your username is banned. I recommend contacting the support team to ask for clarifications regarding this issue. They are able to provide a status for your username and passwords.
