Unfortunately I had a very similar experience to Cecilia. I had to reinstall windows also and I had backed up the original installer file. Unfortunately the original installer file no longer works, as it calls back to Stardock servers and doesn't allow re-installation without a current subscription. Stardock's own knowledge-base even says that any installers you have will continue to work (and this is the only installer I ever received). Their customer service has the audacity to say that this installer is just a "manager" and you have to find and backup the smaller individual install files that the first installer downloads into a stardock folder on your PC when you initially install it. This is such a pathetic excuse and honestly terrible business tactics. They've lost a paying customer now, never again will I purchase from them. Now I've seen similar reviews on a few website, I feel silly for not checking first.
