Hi there, I seem to have similar problems. I have the same configuration although in my case the program crashes when it tries to defrag "offline files". I have tried it a few times on two laptops, and both will crash while doing a full defrag with "offline files" on the disk,.. but both defrag fine when I disable "offline files". Due to work related restrictions I can not attach log files, unless it still helps you if I can replace critical project and file names with dummy names.
Defragging files and quick defrag seem to go flawless by the way.
