Can you send us your Skyline document and one of your Agilent raw data (.d) directories?
In Skyline you can use the menu item:
File > Share
to create a .sky.zip file containing your Skyline document and supporting files, including extracted chromatograms.
If that .sky.zip file is less than 50MB you can attach it to this support request.
Otherwise, you can upload it here:
You should also zip up one of your .d folders with your Agilent data.
One reason that you might be seeing "Chromatogram Information Unavailable" would be that there really was no chromatogram in the raw data whose Q1 and Q3 values matched the precursor and product ion m/z's in the Skyline document.
After we see your Skyline document and raw data we will probably be able to tell you what is going wrong.
