I had the same issue and the support ticket did help resolve it. Ultimately the issue was that they only allow specific special characters in your password, but they don’t specify that when you’re creating a password. And strangely it works for the website, but not for the software. For reference, the characters that ARE allowed are here: . ? @ $ ^ * - Perhaps check your password and try changing it.
