Audio Input Error

I get this message as the Project is Opening but am not sure what to do about it. It’s not specific and when I look at my audio setup and connections everything looks OK.

If I choose NO, it complains every time. If I choose Yes…? Error is gone, but not sure what changed.

That is certainly a bug. Did you change your hardware recently? The message also implies that you use Stacks, correct?
Would you mind to PM me the project (just the .vlprj file, no content etc)?
Sorry and thanks for reporting.
