I am in the same situation as pj123 as when I try to update I also get the "No updated components available"!
My definitions are SE1R20 and dated 25-11-2004. Does anyone know why I can't update anf if so how can I fix it? Should I uninstall it, reboot and reinstall Ad-Aware SE? I don't know if it makes any difference but I am on AOL Broadband?
