Audio in quizmaker is lost when files are copied
We have a number of quizzes (11 in total) using Quizmaker that are part of a Presenter file. The audio is recorded for the question as well as the responses. The audio can be heard and played back after recording. However, when the ppt & ppta files are copied over to a central drive and then copied to another c:\drive for the purpose of publishing, all audio in the quizzes is lost. The audio recorded for the ppt slides is still intact.
Can you please advise why this is happening and how to stop it?
