I have to problems now, I changed PCs:

1. the project files used to be on D: drive, but the new computer has only C:
so i guess u know what happens when i try to open the project.

2. I tried the project on another PC and the WMV videos i used doesnt appear

I'm guessing that when you open the old project on the new pc, all of the video clips in the library space have a yellow rectangle in the top left corner of each thumbnail, and you are presented with a message telling you that a video file doesn't exist. You are prompted to re-link the clips, and if you have them all on your new pc, on the C: drive, you just need to click on the "Relink" button and browse to each clip in turn. The project will then be restored.

i fixed that, now i have a bigger problem
when i try to publish the project as a video, at about 14% it gives me an error saying unable to lead library or something like that
