So, that was so ... after I installed the new live update, I flew to cyvr. there was the above-mentioned problem. then I completely uninstalled the scenery and downloaded and installed the current installer via the fsdreamteam hompage. I still had the proplem. After some experimenting, I then uninstalled everything again and took a cyvr installer, which I downloaded before, I believe, four months or so. it worked. all buildings and textures there. but as soon as I install the live update, the problem is back.
