Big shout out to Julian Heller (aka fluxer555) for his awesome recovery service!

I had an old corrupt PTS wallet from 2014 and after trying to extract the keys via multiple methods including bitshares 0.9.3c and pywallet, I decided as a last resort to give it over to him. He managed to salvage the private key from the corrupted file and was excellent at communicating over skype, I wholeheartedly recommend his service if you have a wallet which is corrupt!
