Purchased, installed and activated Expression Web 4 in a Windows 7 Pro environment. After a few days using the software, I am getting the activation pop up window again saying: "O day(s) remaining for activation, new product enter key and click continue; already activated click continue. In either case it exits. In the former, that is after you enter code, it says invalid code and exits. It the latter, already activate, it says "already activated" and exits.Eddy Guerrier
