1. Just want a quick confirmation that these are the correct ones. There were some news about the Windows 10 Store having some fake apps. Are the links below the legitimate apps for Vegas Movie Studio 15 and Vegas Edit Pro? Just want to be sure:

https://www.microsoft.com/en-us/p/vegas-movie-studio-15-windows-store-edition/9n5bl3g94jk0?activetab=pivot%3aoverviewtab

https://www.microsoft.com/en-us/p/vegas-pro-15-windows-store-edition/9pgsx9cnh3nq?activetab=pivot%3aoverviewtab

2. When new versions of your app on the Windows Store come out, what happens to the older ones if we bought them through the Windows Store. So if I buy Vegas Studio 15, and 16 comes out, will I still be able to download the 15 that I bought if I have a new computer?

Thanks is advanced.
