@Jac.obj, not sure what's going on with your install, but a simple solution would be to download the Corona installer, whatever version you're using, and run it. It will replace all that stuff and, as I mentioned previously, when Cosmos comes back online, it will see what assets you have downloaded and all will be well. Too bad this is a constant issue now. Any time I see Cosmos pop up with an update "It will only take a few seconds", I don't click those anymore unless it implies a major update. Those few seconds turn into never ending ball spinning.
