"Initializing, Please Wait" on SEP Manager Web Console

Hi there

Am getting the error that is in the Subject title of this post.

I get this whether trying to access the Web Console from the server itself or from another Windows Client on the network.

Have tried multiple browsers, IE10, Firefox and Chrome.

Have added to Trusted Sites

Have followed steps in other posts to change the regestry keys relating to the Java heap sizes

Am running 12.1.1101.401 on Windows Server 2008

Thank you!
