Hi Alan
Did you get any answer by now? 'Cause I am running the very same configuration as you do and bought "Leg 727" (and Leg 104) just yesterday. I have not yet been able to activate it (time-issues), but hope to do so this evening.
I guess (learnings from the faq-page), following issue might occur:
- firewall/antivir can block the activation
cure: close down "defender", shut off vir-screening for a while, and turn off firewall (how? it is in the router...)
Hope that will do the trick - or better: no issues!
I am not quite sure, if activation offline would be better - I thought of trying to and doing the "online-part" here from my office pc, but as that one is secured, which I am not allowed to change or turn down, I am afraid that would be of no benefit...
So, cross your fingers........
If anybody else can comment or help, go ahaid!
