SpywareBlaster user type update

I have used W2000 now I've got XPpro. I cannot get the update to work when logged in as a normal user, it did work when I had W2000. It only works when I'm logged in as a admin user. I've tried changing the user to a power user - able to change some (not system) files, but still not updating.

I can't remeber how to make it work, was it with special folder sharing or user permissions in W2000? My W98se machine works ok, that's how I know I'm behind with updates on the XPpro pc. The message I get is " ... no updates available ..."

Any ideas?
