Where to download old versions?

Hi all!
First of all sorry if this subject was already solved, i tried to find info in the forum but i didn't get it.
My problem is simple, the CD who came with the U-Mix Control Pro is broken and i need the old version of Cross DJ (1.5) in order to activate it with my serial number. Does anyone knows where to download the 1.5 version? or how can i use my serial code in order to activate any downloadable version of Cross DJ?
Thanks a lot!
