License error for all .acsm files

Error getting license. License Server Communication Problem: E_LIC_LICENSE_SIGN_ERROR

This error is happening for every .acsm file I try to download from Archive.org

It just started happening. No issues before this. I've updated ADE, de/reauthorized the program. Cleared cache and cookies. Nothing works.

Anyone else having this issue? Suggestions on how to fix? This is very frustrating.
