License & Web issues

Hello,

Our website disappeared recently. I noticed that the wordpress theme was saying “the license for Theme Esteem” had not been activated. When I entered the license info, it said it had no account. I had to renew the service but the license, and it is still saying it has no account. I tried to reinstall it on the site, says a file already exists. Suggestions?
