yes, client.exe has admin permission. I also have tried it in compatibility mode for Windows XP sp2, Windows 2003, and vista with no luck. I uninstalled the client, and then when I tried to reinstall it, it wouldn't open a browser for the key, so I had to install it under windows xp. The latest problem is that the patcher keeps redirecting from the client's folder (C:\EnB\Release\) to E:\Program Files\Electronic Arts\Earth and Beyond\release and then trying to download the entire game through the patcher. Still no luck resolving the original login problem, but it does seem to only occur when running vista, I didn't have the same problem in XP or 2000 SP 3.
