My new tent's rainfly failed in a light Oregon drizzle

I was camping near Bend last month, and a forecasted 'light mist' turned into a steady rain overnight. About 2 hours in, I felt a cold drip on my face. The seam sealing on the brand-new 'Trailblazer 2P' tent's rainfly was leaking right along the main ridge. I had to spend the rest of the night with a cooking pot on my sleeping bag to catch the drips. Has anyone else had a tent fail on its first real test like this?
