Blender Export as Run Time error

Hello, I’m having a spot of difficulty trying to export my game as an exe.
Every time I’ve try I just keep getting this error message HERE

I’m unsure what the issue is, but suspect it may have something to do with the file swapping process during its development. While constructing this at college, the files were sent back and forth between myself and my tutor which created a few pesky image.001 (.002 etc) files.

Does anyone have any idea how I can fix this blend file for exporting?

Thank you for any help.
