If the scheduled recording failed, and there's a message saying so, you should reinstall Debut, make some tests, schedule a recording in the next 5 minutes and check if it starts or if you get the error message again. If you still get the error, you should enter a support ticket at http://www.nch.com.au/support/supportcontact.html Make sure to include your Windows version, registration code and Debut version (check it at the bottom left corner of the program).
