Hi Dorota,
The sky.zip files had been moved to the "SupplementaryFiles" directory where the data validator was unable to find them. This looks like a bug. Thanks for reporting it. I have moved the sky.zip files back to the original location, and rerun data validation. You should now be able to see the raw files and search results files used to build the spectral libraries. These files will have to be uploaded to the "Raw Data" tab if you want a "complete" ProteomeXchange submission. You can see the latest data validation results by clicking the "Submit" button in the "Targeted MS Experiment" webpart.
Thanks,
Vagisha
