DOWNLOADING DATA FROM SITE AS CSV NOT WORKING

I frequently use a site airtable.com where I have data that I download every month as a .csv file. In my previous browsers this download has never been an issue, however it is an issue in CCleaner. It says preparing download, but nothing launches for me to download. I've added the URL to my whitelist, have flash allowed and pop-ups allowed, yet can't get the download. Can you please advise on how to fix...this is a huge issue for me.
