Yes, but I had uninstalled SODE 1.4.2 prior to installing 1.5.
Anyway I have found a strange thing: I have 2 FSDreamteam sceneries and XCity Rome by Cloud9, THAT I HAD DEACTIVATED, pinned on top of the scenery library and they can't be deleted or deactivated! Further, the sceneries have been moved from their initial location inside P3D to the Addon Manager location, that is where I installed GSX, outside P3D. I guess the problem is XCity Rome, but how can I disable it? It is NOT in the Scenery.cfg file!
