A few months ago I accidentaly wiped my computer.... also I misplaced my cds ... Avernum 4 is coming out. BUT, to refresh my memory I want to be able to play the previous three, which I have bought, although they are no longer on my computer and the cds are lost. Is there any way to get the cds or just the codes or maybe even new cds or codes without having to buy the game all over again?
