Hi Helena.  It sounds like you might be seeing this red X due to the file size, or it's possible the file could be corrupted. 

Please make sure you are following the guidelines for working with Storyline content as described here. 

You may also want to try importing your files into a new Storyline project to see if that helps.

Please give us a shout if you need any more help.
