I/O read error

Hi All,

  I just lost 3 days of work as I can not open the latest file I was working on, keep getting I/O read error.  File was created in Corel draw X6. sized over 92.800KB.... I use windows 7 Home edition.  I tried to recover it from temp files but doesn't seem to saved a back up file.

I’m an artist and use computers extensively but not too good with techy stuff.  I downloaded Recovery Toolbox for Corel Draw but that didn't work either.

can anyone help me fixing it please .
