Still get 'Shared Folder Not Available'

Question

Hi all.  I posted a message around November 15, 2009 and never received any responses. See  http://forums.linksysbycisco.com/linksys/board/message?board.id=Network_Magic&thread.id=1488   That was for my laptop and problem never resolved.  Now I have a netbook, same problem.  Both computers see the enabled folders on the desktop and I can access the folders on the laptop and netbook using Windows Explorer.  I can also access the laptop and netbook folders from the desktop using Network Magic.  But I can't access any desktop folders using Network Magic.  I get the dreaded 'Shared Folder Not Available' message.  I've checked out many threads here and through google search.  I've made the recommended configuration changes to Norton Internet Security.  I've disabled VPN software at the recommendation of the tech who installed the VPN.  I've contacted Pure Networks and submitted a ticket--was given standard things to try--nothing worked. 
Does anyone have something else to try?  It seems a big waste to have spent $50 on software that doesn't work for my machines and whose technical support people don't seem to have a solution.  Please don't respond that it must be a setting in Norton--I've tried changing everything recommended. Norton is one of the most commonly used firewalls and anti-virus programs around.   I'm sure other Norton users are successfully using NM.  I will try contacting Pure Networks again.  Maybe a different tech will have a solution.
Thanks for any help you can provide.

Well, thecreator, I did provide the requested information the first time I posted in November.  If you go to the link I included in my current message, you will see that the information was provided or see extracted information below.     I also understand that no one may have a better answer than what's already been posted in the forum.  If the information I've provided isn't sufficient for a response, I guess I need to try Pure Networks support again.
From prior post:
 "I can access my desktop computer folders through Windows Explorer, but I bought NM so I could use it, not to have to work around it. I would appreciate your help in fixing this problem.  I did install the latest Microsoft updates (November 10 release), including KBs: 973704,975758, 973475, 973443, and 969947  
-My version of NM is 5.5..9195.0-Pure0
-OS is Windows XP, SP3
-My connection is a cable modem and I'm using a Linksys WRT54G router.
-My desktop connects with a cable and my laptop connects wirelessly
-I use Norton Internet Security 2009 as my firewall and anti-virus
-I use SpywareBlaster and Malwarebytes for anti-spyware/malware
