Contact updated externally. Changes will be lost and the viewer closed
I am having the same problem. I installed Missing Sync for Mac version 2 (biggest mistake ever) and now I have all sorts of problems, even reverting back to Missing Sync for Mac version 1. Anyway, the least of these problems is as you describe:
1. Contact does not exist on the desktop
2. Contact will not delete or edit on the device with message: 'Contact updated externally. Changes will be lost and the viewer closed'
I've done all the usual stuff. I do not want to wipe my device and have to setup all my wireless access codes again and go through various email filetring set ups, third party software activations etc etc.
Please help.
