Why isn't spybot being offered the 1.5 update?

I have 2 machines. Both running XP home. One I use and one for my other half. Both run XP Home. Both are connected to the internet via the same router.

After using the update button on spybot on one machine the other week it updated itself to v1.5. So I did the other machine as well and that was not offered the update. I have tried a few times since and although it is being offered updates (which I get) the update to 1.5 is still not being offered.

Is it just a case of being patient? or is something incorrectly configured?

why its not being offered to download the newest version of spybot. In any case, download the newest spybot version from the home page of spybot. Or download it from download.com. your choice. I would uninstall the older version first before applying the newest version.
