Friendly error on login if not licensed user

If your user login is changed from Licensed to Disabled, when you log in you just get a MetaData error:

Unable to load metadata.
[object Object]

Console shows Error 401/HTTP 500 loading https://api-v1.prospect365.com/EntityFieldFormats

Could there be a way to display an actual message e.g. "You are not set up as a licensed user. Please speak to your CRM administrator".
