We cannot see anyone's keys, when you play cRPG it generates a new fresh ID specifically for cRPG.
You'll have to try and check your registry database to see if the old key is maybe still around in there, otherwise try and check your emails maybe.
If you send me a PM with the name of your old account though, and some info that can verify that it is indeed yours I'll look into transferring all your items to this new key.
