I am having the same issue too. What I'm finding is that if I use the Task Scheduler, it works well in Sync'ing but only when the file I'm trying to sync is closed. It does nothing when the file is opened.
Ideally, I would want to not have to close the file all the time.
Wonder if somebody has a suggestion on how to get around this.
The file I'm dealing with is a Microsoft Projects file *.mpp.
