Combat Commander Europe-Spanish.vmod

Hi
I’m trying to install the spanish translation and when I do it, Vassal shows me the next message

This module cannot be opened because it contains “custom code” that references VASSAL classes, methods, or fields which were announced as deprecated more than a year ago and have since been removed

What can I do?

thx

That module needs to be updated to work with the current version of Vassal. Have you tried contacting the maintainer listed for that module about updating it?
