A CAPX is just a ZIP file, so make a copy, change the name to Hei.zip and open it up. Copy everything out to somewhere else. Now you can navigate to the Textures folder and you'll see that Tile3.png is missing. If you can figure out which image that is, put it there with the name Tile3.png, or just put anything there for the moment with that name. Open up the "New Project.caproj" file and tidy up your Tile3 object.
