Extension Warehouse not opening

Hello Friends, Extension Warehouse and Profile Builder extension fail to open for me. I have uploaded the latest SketchUp version, but it still does not work. Any advice please?

Try e.g. this:

Unfortunately it did no work. I tried all the methods you described in the link. When I hit the Windows key and the right arrow, SketchUp moved to the right on the screen but there was no hidden window for the Warehouse.
