I have a similar situation, however, I forgot to unencrypt files before I
reinstalled xp. Even when though I have the same user name and password, I
still don't have access. (fortunately, there are only a couple of files
that I would like to have, the rest I have backups). I have been trying for
a month to solve this dilema. Are you saying there is not way to recover
them? If so, I can give up! LOL
