My site and account just vanished today!

Hi. I downloaded wordpress to my TSO hosting. all fine. Was given my account name and pw. I uploaded my theme and put all the content on my site. It was still active this am and I could see it on claritymc.com and I could log-in at claritymc.com/wp-admin but then this afternoon – it was just gone!

WordPress is still uploaded fine to my hosting – so issue with hosting or domains. All fine.

I can’t even log into my wordpress account! I can’t log in via the login link in the hosting area – nothing! It is as if my account just vanished and I had a lot of work done on the site!

Where is it??? Any help how to retrieve it? The automatic form doesn’t work as it can’t find my account. Which is quite silly really – if I had an account I would need to find it!

Please help!
Thanks.
