There was another issue with Cosmos which happened to some of our users. Some assets were not showing up at all. For example, upon checking the Materials > Fabric category, some users were getting only 10 materials there instead of the expected 400+.
The solution is to simply update Cosmos. You should automatically get a message asking to update Cosmos soon after launching it from the Corona Toolbar. If it does not show up, try clicking the "three dots" button and then About. This should tell you that either your Cosmos is up to date or needs an update. Also please make sure that you are signed into the Chaos License Server.
If the above steps are not working, try stopping the Cosmos Browser by searching for "stop Cosmos" in the Windows Start Menu, and then restart it by searching for "start Cosmos".
Usually it is just a matter of updating, but if everything else fails, please contact us at
