Axure missing image's links

Hi guys,
I need to make some changes to a file that another agency created.
The agency sent me the Axure file with also the assets of exported imgs but, when I open the file, I can only see the pages but not the content, like it’s missing the files. Is there a way to link them back?

Thank you

Hi Francesco!

Could you tell me a little bit more about this issue? It sounds like when you open up this file, you can see the page names in the Pages pane, but the page contents appear to be blank. Is this correct? Does double-clicking on one of the page names found in the Pages pane allow any page content to open on the canvas? Would it be possible to share a screenshot of where the content is failing to appear?

Thank you!
