I was doing a website preview, when all of a sudden the preview did not come up. I closed the preview window and the whole program just closed. when i tried to reload the website it gave me an error saying ' the specified project is in use or has not been closed correctly. Do you want to continue? then I say ok and an error notice comes up. An error occurred while loading Project. I even trid to load the backups but it is till giving me an error. This is an important website for me but I cannot access it. Is there a way to retroeve it?

thanks
