I bought Vegas Pro Even more creative bundle from humble bundle on Dec 13. 2018 and redeemed it that day. Back then I wasn't required to make a Magix account and had downloaded it through a different website. Because of this my serial number is redeemed. I wanted to open my Vegas pro 5 today but I got hit with "The code execution cannot proceed because MSVCP110.dll was not found. Reinstalling the program may fix this problem." So I'm on this website now and can't register my code because its been redeemed but its also telling me to activate my code but it has to be active since its already redeemed.
Name: Vegas Pro 15.0, Movie Studio 15.0
PC: Intel i7-7700k 1070 GPU 32GB ram Windows 10 operating system
TLDR: I can't download my software since it was registered on a different site and I don't know what to do or how to retrieve it.
