No matter which thing I click on - interaction, quiz, package - I get the message - The narration file for this presentation may be in use by another program or user, or it may be read only.
I used a different presenter file that I have as the base for this new one but I have saved this new one File/Save as. Is this causing me problems? It is a large deck of about 150 slides with video and such. I can't even create a new quiz or package the file. What to do?
