It seems you knew that pretty well that Covid-19 ate your homework, and Covid-19 won't eat cyberlink's homework because you have PAID to cyberlink.
Cyberlink already has your money to protect them from the covid-19's impacts, and completely won't be impacted by covid-19 because the money you paid to them has magic and medical power to build the protection. Your money is more powerful than a doctor and medicine I guess.
Yep, you have your right to file a complaint to BBB, and BBB definitely has a way to resolve the issue you received in cyberlink program as BBB has no.1 engineering team in the world.
Everybody should be taught how to file a complaint, then things will be fixed right away by filing complaints.
Let's go and file many complaints then everything will be done. It sounds very easy and wonderful.
Being a contributor user here for a long time, I have seen many guys like you love making things aggresive and nasty just because you have received certain issues that others didn't after you purchased the program with couple bucks.
For the prorgram issue you got, if the problem got resolved temporarily after adjusted some settings on Windows, then broke the other day, it is suspected that the issue might not be caused by cyberlink youcam but something else on your PC as youcam doesn't change a bit or update the program recently.
If it is the case, who should be blamed?
If you really need a refund, you can apply refund after you purchased within 30 days without filing any complaints.

But, I believe it's not you wanna do.
What you really need is grab someone for blaming and find a place to put your anger on.
BTW, I can record audio using youcam 9 normally on my window 10 laptop. fyr.
