[Download onto new computer]

Similar to the initial question.  My old computer where I initially installed Affinity photo has died.  The drive failed and can't even be read.  Apparently my software isn't registered on a device.  And the product agreement says I can install on computers under my control.  So no problem with the software still being installed on the old computer's drive, even though it can't be accessed?  I can just install it on my new computer when it arrives?  

Also, regarding the installation email, apparently it can't be updated or changed.  So I only need the old email address and key for installing the software on the new computer, even though I no longer have access to that old email address?

Thank you.
