I have a new computer with bucketloads of memory of all kinds. I installed Movie Maker, restarted the computer and attempted to import an avi movie (jpeg images can be imported without a problem). I get this error: "Adding clip(s) failed. Please check for free space on your system drive. Also it is recommended to use the Convert Video quick tool to convert your video clip to MP4 format." The same avi files can be imported without a problem to Movie Maker in an older laptop with Windows 7 that has far less free space, and much less RAM.

Suggestions welcome.
