Session and all files disappeared...Is there any way to recover?

[jameslenger]

I had been recording over the last 4 days and had no problem opening up the session I was working with. I had been saving every half-hour. I tried to open up my session this afternoon and it appears as though everything has been erased and there is only a "shortcut" to the file I once had. Has anyone had any problems like this? Is there anyway to recover these files? I have searched everywhere in the computer and tried to click on the backup file folder but nothing happened. I am using an MBox 2 an a PC running Vista.
