Sony HDR-CX160 won't import into iMovie

Hello! I am desperate for some help. I have had the Sony HDR-CX160 for over a year now. When I first got it, I remember having difficulty with iMovie reading the camera. I found a Youtube video that told you the order to hook everything in and it worked great. I was able to import my video with no problem.

I am once again having EXTREME difficulty. iMovie will absolutely no read my camera. I hook it up and it boots up iPhoto and even imported pictures off the camera. In iMovie, it shows that it reads the camera, but there is a weird error symbol next to the camera and it won't boot up the import screen no matter what I do. I'm inserting a screen shot to show what I mean.

Does anyone know what I can do? I recorded my friend's birth of her son and now I can't get the footage off my camera which is very nervewracking and stressful for me. Please help!
