I have Personal Plus 2015 and yesterday needed to do a complete Windows reset which removed the program. I have reinstalled up to where I have keyed in the installation key and now I get a message saying the program cannot be installed on more than one computer and I need to pay for another license etc. This cannot be correct surely. I have not installed the program on another computer, I am simply trying to re-install the program on the original computer. What can be done about this please?
