Can't upload video from my camera

Question

I'm trying to upload a video on to my lap top from my camera. All the other clips uploaded fine except for one. It's a 5 minute clip, longer then any of the other clips. The camera is a Canon powershot SD400. When I try uploading it says "The current picture (video) could not be copied, to copy picture click "try again" to stop copying click cancel" No matter how many times I click try again it instantly refuses to copy. What could the problem be? I was planning on making a video and this clip is the most critical piece to show my movie.

Answer 1

Rather than use the software supplied with the camera just drag 'n' drop with Windows Explorer.  If it doesn't work you should at least get a useful error message.
