My friend sent me a .caproj file and I can't open it. what appears is a error message saying:
"Failed to open project"
Cannot find object texture file 'background.png' in the project texture folder. Check the file has not been renamed or removed. Under Element: c2project/ object-folder/ object-type Line 53, Column 9
The file may be invalid. Try checking the file in a text editor. (Projects are saved in XML format)
What does this mean? How do I fix this?
