SharePoint 2010 Workflow Woes

Was trying to run a Workflow on a SharePoint 2010 Document Library and was greeted with the following error message:

"The form cannot be rendered. This may be due to a misconfiguration of the Microsoft SharePoint Server State Service. For more information, contact your server administrator."

I can't find this so called 'State Service' anywhere but after searching the Internet for a while, I discovered that we can solve it by re-running the Configuration Wizard.

Central Administration -> Configuration Wizards -> Launch the Farm Configuration Wizard -> Start the Wizard.

Make sure the State Service is checked and click Next.

Somehow, my SharePoint didn't configure properly after the installation because it timed-out when running the Wizard. So running it again (and made sure it ran successfully) solved the problem.
