I tried this. 2 Things happened. It did seem to update the libraries but when I clicked on SDC/Tools/Refresh Site Updates, nothing took place. Secondly, I re-opened the Settings and found that the 'Clear Recent Skin and Themes List' was unchecked, even though I had previously checked it. After repeating this procedure a few times, I found that it always came back as being unchecked when I would close and re-open SDC. I don't think the problem was fixed.
