Can't configure network security map

2 days ago i started a trial of nis 2010.the only problem that i had was with the network security map.every time i pressed the button a pop up said that i have to initialize a network component then i pressed continue and after a while the pop up said that it had an error with the details(from the one click support) module:5011 error:2

i  uninstalled with norton removal tool 3 times and installed without any progress.today i was about to give up but i accidently found the trial for nis 2011 and i thought that maybe the problem will be fixed with the new nis.well, i installed the new nis the problem is still there but the details have chaged: module:5011 error:4

 

my laptop works on windows vista and i had installed nis in the past  without having any problems.

thanks in advance!!
