Can't create a new table from uploaded file.

I've just started using the Community Edition through the AWS marketplace and I'm trying to set up tables to share with a customer.  I've managed to create 3 of the tables, but when uploading a small version of the fourth file, I'm having problems.
 
The original file that I want to upload is 14 GB, so for testing purposes I cut it down to the first 1000 rows (and then 100 rows when that didn't work).

It shows me a preview for 50 rows and 539 columns, as expected, and there aren't any error messages that I can find on the page.  I've tried auto-detection of column types and also turning it off, with no change.

However, I can't create the table:

Any ideas of how I can figure out what errors I need to fix?  Thank you!
