Issues uploading a Captivate file to my LMS

Good afternoon, I am having issues uploading Captivate files to my LMS. My LMS support has looked into this and discovered when they opened the zipped file, in the Assets folder, there is a sub folder, Playbar. In this folder their is a file called playbarStyle.css that is empty. It has Zero Bytes. The LMS is unable to read this file and move forward. Does anyone know what this file is and why it is empty? Thank you in advance […]
