Corrupted X5 cdr file - Tried about everything with no success - Does CorelDRAW Repair Kit work?

I've tried the .zip rename and unzipped with winrar, found the riffData file and renamed it to riffData.cdr but no cigar - its still telling me that there is has encountered an invalid argument or something like that - and so I now trying to use this CorelDRAW Repair Kit, but wondering if it actually works.  The program says to try it before you buy it, so I spent 6 hours having the corrupt file (original) analyzed, after that a thumbnail showed up that had the content is layered image, seemed good, but now after purchasing it I find that I need to spend another six hours doing it all over again.  Any suggestions?  Thanks,
