Free account closed, subscription status is inactive. Never cancel any service.

Good morning. The machine I have a lot of information on has shut down, and it won't let me turn it back on. It tells me my account status has expired or something like that. I urgently need the service reactivated. I never canceled anything. I only have a free account, and I haven't exceeded my account limits.

I'd like to be able to reactivate the service. And for everything to be back to normal, and if possible, find out the reason why my account was canceled so it doesn't happen again. Thank you so much in advance.
