Aperture - lost serial number
Eric Jervis
For a reason I can't recall, possibly because I bought it on the internet, my copy of Aperture requires me to enter my serial number every time I open it, so I copied it into 'Notes'. Today I accidentally deleted it and can't undo my action.I went into Time Machine, copied Notes to the desktop, opened it only to find that the number was deleted there too! Any suggestions welcome.
