This was my original problem updating 1.5.
http://forums.spybot.info/showthread.php?t=17538
Updated to 1.5. By uninstalling 1.4 1st. Didn't want the double entry in A/R. Running XP VLK SP2 32bit.

Downloaded like 10 updates. 2 remaining updates kept on failing. Dl'd the separate 2007-08-29 update package.

Checked within SSD for updates again. 1 update was left. And the Immunization datbase from 2007-07-25 returns !!! bad checksum ! error. Tried like 8 different dl locations. All fail.

Help please.
Now I hardly use my Windows XP partition. So I guess I missed 2 SSD updates. And now repeating all the same rigamaroll as quoted above. I still can't download Startup info db 2007-09-26. How can this be fixed? Thanks.
