I really need help making a workflow using sharepoint,

I downloaded the train version for sharepoint and noticed there wasnt "create a workflow" when i click FILE, then NEW.

So i registered it and has the same problem.

Then i uninstalled sharepoint and downloaded microsoft office sharepoint designer and i still cant create a workflow.

What exactly do i need.

All i want to do is create a workflow that allows a user to create a page and edit it.
