I GOT the same message,too,when trying to download a newer version of ad aware.
I have been having trouble with ad aware SE personal which keeps saying "error in retrieving update."
I thought I'd change to another free version of ad aware 2007(?).
But couldn't download it.
I just go back and use my SE personal-even though I can't get latest update. I've had no crashes and it rids the various spyware,adware,malware and so on...
But you hear that unless your definitions are totally up-to-date hackers/spammers & other nasty folk! can beat the system?
Is this right?
I hope Lavasoft don't mind-but i always have another free spyware remover as back-up. But I find SE personal great.
