Lost last version KHP

[leecoprod]

Had my last update of KHP on single disk from original download. This past three weeks I had a computer hard drive crash and had to be replaced. All of my MTU products were fine to use to reset the computer except for my lastest verion of KHP, the damage had been damaged due to heat and will not even fit into the disk tray let alone load. How can I get a copy of this back for my personal use and how much will it cost? I thiink I'm gonna need to start using my ii dowloads on al the softeware and burn that many copies so ik don't lose them.
Thank you if anyone can help me.
