chemstation does not recognize the library

Hello. I operate a software "ChemStation for LC 3D systems" version B.04.03-SP1 (87). My problem is that in the "Data analysis-data" part it stopped recognizing all the subdirectories and the chromatograms that are inside them, except for one. These were not deleted since I can access them through windows explorer. How can I get them to recognize them again? Attachment screenshot.
