I have used Sony Vegus for about 4 years now and it's great. Now using 8 Pro and also bought a HDR - HC7 camera. Taken my first project, loaded into the comp and all the clips are greyed out. I upgraded to Vegus pro 8 0b installed a patch that I was assured would solve the problem STILL THE SAME GREYED OUT CLIPS

Please can someone help me What have I done wrong?????
HOW DO I SORT THIS OUT
