Defraggler Problem

When I run Defraggler on a friends laptop, I click Defrag and it starts building the file list and gets to 15% and doesn't go any further. I've downloaded the newest Defraggler to see if they helped but nothing. I've even uninstalled it and reinstalled but still have no luck. Does anyone know what's going on or how to fix it? Thanks!

Where you downloaded it from? I guess someone will tell you to run the debug version and post debug log here. It can hint important things to developers.
