The Active Directory schema version for this domain and the version supported by this tool do not match. The GPO can be restored using the /ignoreschema command-line parameter. However, it is recommended that you try to obtain an updated version of this tool that might have an updated version of the Active Directory schema. Restoring a GPO with an incorrect schema might result in unpredictable behavior.
