I ran a demo version of MB (version 184.108.40.2060). Unfortunately I've the same problem as Arthuru that access to shared folders on other PC on my home netwerk is impossible. I ran the MB-demo on a PC and a laptop. Both now have the same problem. Os is Win XP Pro with SP3. All PC's and laptop do have auto-logon. An uninstall of MB and my virusscanner Bitdefender Internet Security 2011 didn't help. Any suggestions?
