hi folks

need some help with a problem(s)

using windows xp home. and aol broadband

when logging on using xp administrator account i get a window titled hdreg - runtime error '53': file not found
when logging on using xp non-administrator acconut i get a window titled hdreg -runtime error '70': permission denied

aol will only launch with xp administrator account

q1. what are these hd reg's and how can i get rid of them?
q2. how can i get round logging onto aol without being having xp administrator rights(for the kids)

i have tried aol live help - waste of time. everything worked ok with aol 56k but i have had to to a full system restore between 56k and broadband.

any help mostly appreciated as i am well out of my depth

cheers
