Hi @ravi8308,
You must have the Flash plugin installed and enabled in your browser in order to use KMC.
From your previous message, it sounded like you already managed to load KMC [only you logged in with the wrong user] so I’m a bit confused by this… Please open your browser’s dev tools and look for errors under the “Console” tab and failing request under the “Network” tab. Paste these here, along with the URI where you see these errors [I don’t care about the domain name but I need the path to understand what page you’re talking about].
PS
We’re working on a non-Flash version but there’s no ETA at the moment.
