I'm positive you just need to add a parameterless constructor, EVEN if you don't intend to use it. You could always mark it internal too. I have to assume you're using an xml serializer because in my experience, this has always happened when an object lacked a parameterless constructor. I also have to assume that when you added a constructor with parameters, you removed the parameterless one. Can't do that...as a sidenote, it would be helpful to have explained how exactly you serialize the object for others to better understand your issue.

So basically, it should look like this:
[Serializable]
public class ClassObject : MemoryStream
{
    //Must be present for serialization to work!
    internal ClassObject() { }

    public ClassObject(string s) { }
}
