Return of Reckoning

Hello I need some help! Until yesterday all was ok, today when I launch the launcher all gets stuck on "Downloading (1/4) ... War-64.exe, the CONNECT button is grey and of top left side of the screen I get COPY TO CLIPBOARD which is not working. I tried the repair option but nothing has changed. What can I do..? Should I reinstall the game? Because I read the server is up.
Thanks in advance

check your antivirus/firewall settings.. maybe you had the famous windows update that turned everything back on?

just whitelist whole RoR folder

Do you mean the windows 10 20h2? Nope I still did not do that, hearing a lot of prob. about it, but I ended with a reinstalling the game and now all is ok thank you so much!
