Hello,
Sorry to hear you are having issues. You can refer to this guide to get to your product and keys : https://forums.stardock.com/484254/getting-your-products-and-keys.
As for Betas. It should appeared in your accounts : Link here : https://store.stardock.com/myaccount/products -> under "Object Desktop Manager" -> Click "View individual Downloads" -> A list of all Downloads under ObjectDesktop will be there including all available betas. -> Click on those links to download it.
Try those and let us know if you still need help.
Thanks
