Need urgent help please, I deleted the whole folder including wallet.dat

Although I immediately ran undelete software, Cosanta reports the recovered wallet.dat file is corrupted.

Any solution to recover the coins that I mined for so long and so hard?

My cosanta.net address is CVvbCDPzGUXAZKxDJSWgsHHw5zWaDWJzTz

If more information is needed from me, let me know please. Didn't have a lot of money there, just a few hundreds dollars, but I mined those for months and months so very frustrated..

Thanks
