Since setting my computer back up after moving, I keep getting the error message "The parameter is incorrect" on every MS update I try to install, on system restore, any new program I want to install and even program updates. Everything else is working, but, I have no idea what to do?? The Windows KB talks about parameters, but, if that is my problem, EEK! I am hoping it is just a setting gone wrong? This happens even as administrator - in safe mode I don't get the message, but nothing else happens either. Anyone have any suggestions? Appreciate it, I can't update or use any firewall but XP, not good. Thanks in advance!! Marja DUH! I am using Firefox 9.2, WinhomeXP2, ran all my ad/spyware progs (Spybot,Adaware,Spyblaster,Spyguard,Winpatrol,using XP firewall and ProcessGuardFree) I did defrag and had Sygate Firewall installed, but, it doesn't seem to be working either, A2 won't work,Avast seems all right.) Thanks again for any ideas!
