imatt3000 - Make sure the questions all contain non-empty interactions and distractors. There are multiple ways to do this - but if you've published (locally) with "Include Adobe Connect Metadata" enabled, look for a file with "{projectname}_TRMetadata.xml" and open it. Look for any references where the response is EMPTY:
<response id="1"></response>
(NOTE: It should look like: <response id="1">1</response>)
If you, you may look for that question in the Quiz Manager that has an empty distractor or possible answer. make sure all distractor's have a value.
