I need help my Plutonium launcher is not responding when I open any available Cod game

Not responding as in it just crashes? Are you on windows 7?

Same problem here, am on Windows 7. After clicking play, the bootstrapper launches, and then it and the launcher stop responding.

Yes windows 7 is not supported anymore. Upgrade to windows 10.
