Rhino 7 + VRAY Chaos Cosmos Browser Material Library problem

I have a problem with Rhino 7 + VRAY and Chaos Cosmos Browser

When I open Chaos Cosmos Browser from Rhino 7 and click V-Ray Material Library, I get a message “No results found. Maybe try one of these spaces or go to our home page:”

What I have tried:
Compeletely uninstall Rhinoceros, VRAY, Chaos cosmos and all related and deleted the folders.
Rebooted the computer

Does anyone has any idea how to fix this problem?

Hi! Did you find a solution for that problem?

Yes I did. I tried to copy and replace files from a working installation to a broken one but that didn’t fix the issue. However Chaos Cosmos browser offered me a download link to a newer version of Chaos Cosmos browser. Filename: cosmos_538608_win_x64.exe. I downloaded and installed it and it fixed the issue. Unfortunately I don’t have the link anymore but hopefully the filename helps you to locate the package.

I find Chaos Cosmos to be very frustrating. The connection regularly fails. Chaos directs me to download an update. It fails with a warning that a more current version is installed. Then I use uninstall to try for a clean install it the uninstall fails. Then I go to Chaos where it offers older versions of Chaos - just in case you need to revert - and those fail again because a newer version is installed. What a mess.

Hello, Did you guys manage to solve the issue with chaos library? I am unable to load the material library at all.

I have tried reinstalling the chaos browser several times without effect.

Edit: I solved it by launching the cosmos browser from the start menu, and signing in manually. Then when I launched Rhino, it works now.
