I had the same problem on my laptop that runs XP.
I was fully patched, had the latest Sakray fully updated and everything. I would run the anthem.exe and it would come up with the "VShield" window, but then AnthemRO would never start; I never even made it to the login screen. I spent a week going through the suggestions on the forums, but it never worked. I eventually gave up. I wonder if it might be a graphics problem, but I've never gone back to try getting it to run again.
