Replying to Final Cut Express Help

Just got this program today and am still trying to figure it out, but I'm having problems importing some clips into it. I have an AVCHD camcorder and do all the importing steps as needed, but it keeps stopping when the application queues the video for importing. I has a little red exclamation point in the little spinny circle thing. It has two options when I click the red ! and they are "retry" and "remove". Did I do something wrong with the formatting the first time you open the application? Please help me, +K to helpful answers.
