I am having a constant battle to get past update prompts for new versions of Vegas Pro 19./ Every time I open the program it requests that I perform 2 updates which I have already done, and followed instructions, clicking instal when I close the program, but when the program opens it again, it gives the same messages??

Also if I place a simple .Mov file on the timeline and press play, it says it can't play the requested media, but doesn't say why.I am running windows 11, but the issue was also present running windows 10.

Any guidance would be most welcome.
