Indeed. So, the only things I've done are the following:
1. Install the app.
And 2. Register it with my information.
So you just downloaded and installed the illegal pirated repacked Vegas Pro 8.0, because "1FW-KGP5-BW7P-MEE9" is used to crack Vegas by illegal key generator.
Unfortunately, this forum does not offer support for piracy of Vegas. You can go to the Vegas Reddit, which allows support for pirated users. https://www.reddit.com/r/VegasPro/
