Region Activation Problem

I bought Norton Security Premium in the US for my US PC for 10 PC. 5 PC are activated fine. One US Laptop was expired during by business trip. Now cannot activate the subscription on this PC because the US PC is in EU territory and Norton says this Product is invalid in your region. I mean Norton what is that? I have an US PC running on US Windows 10 registered on my US Address and you would not allow me to activate the 6 out of 10 PC only because I am in the EU right now. Just give me a break! What a terrible Idea. I am strongly thinking to move to AVG since 15 years using Norton. Fix it quick. I will be back from EU in the US not within 2 Weeks!
