The following table shows the different error messages.

#	Error message	Description	Resolution
1	Cannot retrieve any valid asset silo languages. This is usually because the config field on the asset silo item is empty.
2	The following language\|s (x) on the asset silo, does not exists in Digizuite. The synchronized metadata between Sitecore and Digizuite will therefore fallback to the default language.	One or more languages on the Asset silo does not exists in Digizuite. Which means that the metadata synchronized will be the default language, which is set in our configuration.	This is just an "be aware of this". To fix this either create the missing language in Digizuite or delete the language on the asset silo item.
