My main computer just failed and I have to wipe my hard drive with the Evolution 8 program. I did save the install files but the unlock codes do not work anymore. I need an unlock code to install on my laptop AND when I get my computer back with a clean hard drive, I want to install it on that computer again. What do I need to do to get the unlock code? Also, if I want to upgrade to the latest version, what is the cost? That may be more desireable than keeping the older version.
