This happens if your project filename is not the same as listed in the project information.
Often, this happens for one of three reasons:
- You added a filename extension (like.docx) to the project filename because the extension was not displayed by Windows Explorer or the Mac Finder.
- You added an unexpected space to the filename, at the beginning, middle, or end.
- You didn't rename the project file as specified in the project instructions.
Resolution
Find the expected filename under Expected File Name.
Rename your project file and upload it again.
