MOZ DA error CS0012

Hello, I keep having this error. Tried with several URLs.

Connector exception, Error CS0012.

An error CS0012:The type 'System.Attribute' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Runtime,Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.

have heared, MOZ DA should be shut down - is it maybe already the case...?

What version of Seotools are you using? Can you attach a print screen of the "About" window?

Moz still works:
