Thanks You for your replay.
I have done what You said and... IT worked.
But, there is allways à But.
there are still contacts that are not in both files.
when I enter à New contact in Either of them, They are not synced.
If I enter à contact in One of them, and i copy The item, They are not synced.
pfff, so now I have à synced database, But every addition is not synced.
Do You have à Solutions for thuis problem.
thanks
