aspx downloading at each run

Hello,

I need help with the following issue.

1. I publish my Storyline project and upload it to a SharePoint folder
2. One-by-one I download story.html and analytics-frame.html, rename these to .aspx and upload one-by-one
3. I then click on story.aspx to generate the link to be published/run the project
4. At each run it downloads analytics-frame.aspx

The last step is not desirable. Any idea why this happens and how to fix it?
