I'm surprised the date of a file would cause such a problem. Have you tried uploading an older version to Scorm Cloud and then overwrite it with a newer version to see if the problem happens on that platform? If it doesn't, the issue lies with your CRM.
One way around it, if indeed the file date is the problem, is to extract the analytics file from the published zip, open the analytics file in Notepad and add a simple space at the beginning of a line (so Notepad recognizes the file has changed but the functionality of the code isn't changed) and then save the file and replace it in the zip. The file will have today's date.
