How does one opem a TMP file created by Corel in a crash- X5

Okay so we had a crash and the file I had been saving all along for some reason became a blank page.

Left in the folder was a file called @@@CDRW.TMP which I cannot open. The thumb seems to show my original page.

The worst part was I was busy with logo design and had done a whole series of logo's and was on a roll getting idea's and logo sample together - something in the moment you cannot re-create. Any idea's would help please.
