Broken Captivate file

Hi there from South Africa. 

I lost my job due to retrenchment a few months ago. Before I left my previous employer I selected a few files of the work I've done for my CV portfolio to show a prospective employer.

Then disaster struck. I got a bite and was asked to send my portfolio. However, the only two Captivate files I chose cannot be opened by clicking on the HTML file after unzipping it. 

I've googled around and the only reason I can phantom is because I keep all my files stored on Onedrive. Apparently Onedrive is not able to store /support the file extension inside the SCORM zipped package. 

It's happened to me many years ago, but I cannot remember how to fix it. 

I was hoping there is an experienced Adobe Captivate user on here that can help me. 

I'm in a real twang here. 

The only one person left at the company cannot find the two Captivate files in question and I'm out of options here. 

Hoping someone can help.
