Hi Tim,
It seems we have two separate DLLs for reading .lcd files from Shimadzu and Skyline used to expect the QQQ reader to fail entirely on seeing QTOF data, but your file showed us that it might return a success code, but then provide no spectra and no chromatograms. Hence the error about "no usable data".
Matt Chambers, today, made a fix to consider the QQQ reader to have failed in this case and move on to trying the QTOF reader, and my latest build of Skyline can no ready your file and extract chromatograms from it.
So, you should be able to use the next Skyline-daily release (click the green "Skyline-daily (beta)" button on the installation page) with your .lcd file.
Thanks for reporting the issue and providing the example file.
