Spybot update gives "!!! bad checksum !" error

When trying to update Spybot the components of Detection rules: Hijackers, Detection rules: Trojans and Immunization database return a comment of "!!! bad checksum !" after downloading and trying to install.

Can anybody shed some light to the situation? :sad:
