I upgraded to Paralells 12, but had to re-install macOS Sierra for an unrelated issue. Now, after re-installing Parallels, when I sign into by Parallels account, it says I have a subscription, but no products available. I installed a trial version of Parallels, but can't activate it as I don't have the original activation key anymore due to the MacOS rebuild. I do have a receipt of purchase of a subscription. Any help? Tim
