Hello All!
     I know nothing about SketchUp, except that I used to occasionally download a free 3D model from the Warehouse on 3DXchange. I learned to select SketchUp 2008, so that there was no problem downloading.  Now the earliest one you can choose is SketchUp 2017, and I can't seem to download anything.  The error message says I have to use 2015 or earlier, which isn't even an option.  I don't have SketchUp on my computer, and don't think I ever did.  What can I do to be able to download models again?

                                                                            Thanks,
