How do I rectify this My Account Error?

[SophieSweatman]

After a huge amount of trial and error, I’d like to deploy my app for primary testing.

I have sorted out the bugs and got my Account error, telling me this: Nothing I do rectifies it.

Thanks for anyone who can help. 1. apart from offline (already togged off and refreshed) do I need to turn anything else off?
2. do I need to upgrade my account to Premier before deployment? If I upgrade at this point, will it allow me to deploy this app without losing anything?
