Files are Missing!

After being totally down for 2 months all of my accounts were working. At the current time I am on vacation and went in to do a quick update on one of my sites and NOTHING IS THERE!!!! The website is still up but I have NO files. Please restore all of the files from http://www.irresistibleshihtzu.com   into my account in the appropriate place. I have no idea how this happened or how to fix it.. I do not have hours to sit on hold while on vacation on a cell phone that I pay for the minutes.
