I reviewed the report documentation and also the error message you sent about the CSV "stray quote on row 1", so I guess the higher time-out value in your doc of 600 fixed the time-out issue.

The doc also showed a table column named "EpisodeNotes" so I'm pretty sure the CSV structure error is from users embedding double quotes within the text. You'll need to either strip out or replace those characters with some other character using a formula -- or -- choose a different delimiter from available list on on "export options" in design such as a tab character or "|" and then choose option to not enclose data in quotes.

Let us know if that is the case and the suggestion fixes the problem.
