My understanding is Bitcoin Client changed to Bitcoin QT further down the track. The Bitcoin QT interface doesn't look right to me. Wasn't till I found Bitcoin Client interface did the penny drop.
Any Bitcoin client that was used MAY have issued some words after creating the wallet as a recovery for password only feature.
What time of year approximately did you use the client?
