If you're organizing your download dir by addig directories to it, I suppose that's ok... but you don't have to share it manually as it's automatically shared by XoloX. Perhaps it's crashing because you told it to share a directory that's hard coded to share already? I know it doesn't let you share folders twice normally.

While talking of sharing files... please include hidden directories in the directory selection tree, or give me a manual entry box to specify directories it can't see. Thanks.
