SketchUp 2015 64-bit - All files Read Only

I just installed the newest version of SketchUp 2015. It appears the bug fix regarding thumnbails and windows explorer crashing has been fixed. However, there is now a new issue with all the SketchUp files being read only. I know that this is the new version causing this, because the last release did not have this problem. Anyone else having this issue? Are there any known fixes?

Is this something that will/can be fixed? If I can’t use the preview pane and the thumbnail view, it really defeats the purpose of thumbnails preview.
