I have bought Adobe Photoshop CS4 (box, license for 3 computers) in 2009. I've used it on two computers with activation, but one computer had formating, and second I've lost. I don't know how to 'unactivate' them now, and when I trying to activate product on my actual computer - it says that all license keys are in use. I have whole box and papers, even facture as a proof for purchase. What I should do?
