Lost website..

Hello,

Its a bit of long story, but I have been using wordpress for my personal website and it works fine. I had a second website that was a e-shop on a different domain but under the same webhost account. Last month, I forgot to extent the service of my web-host and of course my website went down. I payed and solve the problem there and I was able to reconnect my wordpress site to the domain. However, I have not been able to find the second website, also created with wordpress. I go to the domain and it is empty. Is there a way to find that website again?
