I just installed ADE today -- version 3.0 on a PC running XP Pro. I then downloaded ebooks from my library. When I try to open any of the ACSM files, ADE fails to do the first-time authorization; the error message is
Digital Editions could not connect to the activation server. Please make sure you are connected to the Internet.
Of course I am connected to the Internet. I've tried what I've seen suggested for earlier releases, including Ctrl-Shift-D (which did nothing), re-installing, and making ADE 3 an exception for my firewall. I also find it strange that the authorization screen shows my ebook vendor as "Adobe Id" and doesn't let me change it, or show my library, or whatever.
Any ideas would be apprecitated; thanks.
