did you check the partition boot sector decrypted properly BEFORE doing the force decrypt?
If you proceeded without this test, then indeed things could be hard to rescue - you may have used the wrong SDB file, in which case you need to re-encrypt, then decrypt with the correct file.
we having issue like this when site it try to recover without knowing what are they doing..
which at the end cause much damage that it's should
My sugestion to be carefull and log everything you;re doing..
you need full understanding on what is MEE before doing recovery..
So to point what have got worng could you tell us from the begining on what is wrong and what step have you taken?
