Hello.
I had this problem too and what I did was to add this to the relevant classes:

include java.io.Serializable;

public class... implements Serializable {
.
.
.
}

Hope you get it to work!

Always make sure ALL objects (including any object trees such as nested objects) ALL implement Serializable and always put the serializeableUID variable in every class.
