VectorWorks 2008 SP3 and PandaSoft Global Protection 2009 (anti-virus and firewall) not compatible.
Windows XP Home
VectorWorks 10.1 works with PandaSoft Global Protection 2009
My suspicion is when VectorWorks 2008 goes to check the license, it does so by checking the ethernet port. My internet connection is though my Ethernet port and ADSL modem. Pandasoft firewall and anti-virus program does not allow this to happen, hence VectorWorks is shutdown during its' startup sequence.
