It sounds like you may not have created a sequence first, an easy mistake to make on your first try. Drag and drop the first clip right over that little 'new' icon (looks like a turned-up piece of paper) in the bottom of the project panel and it will create a matching sequence for you and insert the clip into it automatically.
You can also right click on a clip and select New Sequence from Clip.
