I have a desktop and laptop in which I have installed 2008 onto. Neither one of them will register.

-XP firewall turned off
-Date and time is correct, automatically adjusting for DST
-Family tree maker v.16 able to register normally
-previously had ftm 2008 beta version, but uninstalled before installing actual version of 2008.

-Has norton 2004 running, have tried to temporarily disable
