I purchased Movie Studio Platinium 13 a few years back on a different computer. I haven't used it in at least a year and i'm trying to download it but i cant find a link or a way to provide information that i actually at one point owned it. Any suggestions? Thank you so much.
Update: Finally found the "my software" https://www.sonycreativesoftware.com/myaccount/mysoftware. Logged in and it redirected me to magix. From there i just entered in my product key. Wow i feel like an idiot. I'll leave this up in case someone else has a similar issue. Cheers!
The options to download Vegas software are pretty well covered in this FAQ (linked to in the main FAQ section 3.).
Note that for some "legacy SCS versions" (which had later Magix rebranded builds) such as SVPro 13.0.453 and SMSP 13.0.955 you need Wayback Machine as advised in the FAQ (or peer support).
