Spybot S&D gives error message that updater not installed

[chrisluvsanimals]

I have Spyboy S&D 1.6 and when trying to update, keep getting the message that the external updater is corrupted and needs to be downloaded, but when I go to the "updater", there are no updates available from any US mirrors except for English descriptions, etc. which are (I guess) unnessesary. How can I get it to update when it keeps saying I need to run the updater and then there are no updates to apply?
Also get the error message that "Blindman" file is corrupted and need to run updater (which again doesn't find any updates needed)
Running Microsoft XP Pro with all current updates/packages and AVG free antivirus program.
Thanks for any idea's!!
