Hint:

The activation of AAC (MC) failed. if you are using the program as a guest vegas, please repeat the activation procedure with administrator rights.

It's fresh installation and I'am not shure that it's activated OK.

I can't import any "unusual" file for instance made by OBS studio, or converted with Handbrake from ZOOM. What is wrong?????

On older Vegas Pro everything work :)

Thanks!
