Lately as I've been syncing, three-quarters of the way through, the sync fails and I get an error message saying 'Out of memory or system resources. Close some windows or applications and try again.' I'm not sure why it's started doing this. It happens even when I don't have a thing open and my cpu usage is on about 3%! I uninstalled and reinstalled the sync software, and the sync worked once, but it has started happening again.

Any ideas?
