Hi,
What are the file types that you are trying to add? We have a sticky
here about the types of files that Live Mesh will not sync. If the files that you're trying to add to your mesh are not excluded types the next question would be: Is it only files in the new directories that are not syncing, or have all of your files ceased syncing? If the latter, please let me know, but also please collect your logs and submit a bug (instructions are in an Announcement at the top of the forums).
Thanks,
Ben.
