Not now no unfortunately as the encryption is sector location specific. What you should have done is decrypted the drive with wintech, THEN ran the data recovery app.
We did actually try to decrypt it with wintech before trying anything, but it did not recognise the drive at all. That was when we discovered that the whole partition was gone.
That's to be expected - wintech won't fix the partition table. But it will/would have decrypted the data.
Then you just had to run a partition recovery tool to put the mbr back together.
