Unable to login into mywebmethods


I installed my webMethods server 6.5.2 on my laptop. When I start portal server and try to login with default account/pw “Administrator/manage” I am getting back “Invalid user name and credentials” message.

I can login with portalAdmin account but I get only blank page.

SHould I do anything special after installation in order to use mywebmethods for Broker UI?

I configured WmComauth package on IS but it makes no difference.

Can anybody please help?
