Non conosco questa eccezione....cosa significa?

Lo dice la documentazione:

Thrown when the Serialization runtime detects one of the following problems with a Class.

* The serial version of the class does not match that of the class descriptor read from the stream
* The class contains unknown datatypes
* The class does not have an accessible no-arg constructor
