I'll run some tests to see if I can reproduce what you are describing. There isn't any logging you can enable at the moment (that's on my list of things to do). As far as the choices you selected for the sync, you didn't enable the option to check for updated files or to search for new files by chance, did you? Those would likely cause a problem because if the client found modifications or new files, it would try to update the hash file and database in the cloud folder but wouldn't have permission to do that. So you'd want to leave those unchecked. I just want to confirm this as it would be an easy fix.
Thanks,
