Error with file mask_swu

Dear Alfonso,

I apologize for writing so soon after my last message. We were recently reloading/relinking some files that had their directory names (path) changed, and happened upon the below error message. We checked that each subject had the file in question. We also loaded the project a couple of times. We're using the gui. Since these files can't be linked anywhere, I'm not sure how to address the message. I checked through the forum before writing and hope I didn't miss anything.

Message in the terminal background:

SUGGESTIONS:
Potential missing data files or incomplete analyses. Try loading your project again (this will check for potential missing files) or re-running some of the analysis steps if some may have not completed correctly

Thank you and best!
