I was able to play English Civil War just fine a few days ago. Today, when I tried launching, it just freezes on the "War without an Enemy" screen indefinitely. Additionally, every other AGEOD game on my system now freezes on its own respective splash screen (CWII, TYW, Espana 1936 are what I tried). Not sure what happened as nothing changed with my system in terms of Windows updates or anything.
My specs are:
i7 6700k CPU
16 GB RAM
GTX 1070 (I've tried disabling the nVidia processes and nothing.)
