GMod Publishing Utility Problems

So recently I uploaded my server content to the workshop, and a week later, I want to update it. But when I try to update it it goes “File list verification failed, [WARNING] Update Failed!”.
And I can’t seem to find a solution while googleing it. Here’s a screenshot of the software itself.

And here’s the last part of the log:

Looking in folder "C:/Users/Louie/Desktop/Content Pack/"
File list verification failed
[WARNING] Update Failed!
Finished running queue.

Thanks in advance.

Kindest Regards,

One of your files does not match the whitelist. Look though the whole log ( or paste all of it here, using CTRL+A to select all of it ) for messages that are not filepaths.
