Reporting services configuration NO initialization

I am installing sql server 2005 reporting services on server running sql server 2005. I get to the reporting services configuration page and configure...
report server virtual directory
report manager virtual directory
windows service identity
web service identity
database setup
encryption keys
when I get to Initialization the button is grey and inactive so I can't initialize reporting
services, Do I need to restart server?

Hello,

You might want to review what's on the database setup tab and try to reapply the settings in there. Make sure that account has access to the database and that all of the services are started.

There are a couple other posts about this same problem on here:
