Signalrgb app will not login,

Hi, I have been using the pro version for a little over a year. About a week ago I started having trouble signing in through the app. I don’t have access to my pro account. I have uninstalled and rebooted and I get nothing but the free stuff. I can sign in to my account through the website. It there a issue with login through the app? How can I fix this?

Thanks Bruce Cormack
