Game no longer starts after patch, shows a copy error message

After the patch I get an error message about a copy error, and the program no longer starts.

Das Spiel konnte nicht geladen werden, da die Speicherdatei beschädigt ist. Sollte das Problem bestehen bleiben, erstelle bitte einen Fehlerbericht.

This is a mod issue: Could not find field in class at MiningDumpingMod.MDManager

To resolve this, the mod author will have to update the mod for the latest game version.
