For the convenience of others reading this, this is the original topic:
I see now that my message was a bit generic there. So let me state it clear:
Your hosting account is deleted. The reason it was deleted was inactivity. But as I said in that other post: if a suspended account is not reactivated on time, it’s deleted.
As for your question of “can I use the account again”, the best advice I can give is to just try adding the domain to your account. If it works, it works, if it doesn’t work, it doesn’t work.
If it works, then it’s problem solved and case closed.
If it doesn’t work, we may be able to tell you more, but then it would help a lot if you could share the domain name.
