Hi there,
thank you for the comments...
I'm pleased to say I have now managed to resolve this ....
Will F. - i wish I had tried your suggestion (unfortunately, as it is a client LMS we can't 're-try'), as your solution sounds the simplest :-).
What we ended up doing was replacing the imsmanifest.xml from the NEW SCORM package with the imsmanifest.xml from SCORM that was already in the LMS.
Certainly an 'interesting' experience uploading to Cornerstone as there were a few other nuances we had to overcome.... (If anyone else finds this thread and is having issues, feel free to reach out and happy to share lessons learned).
