I've got adobe digital ed. Must be something wrong that it's not opening it? My fault? I've allowed calibre to be the default for acsm files? I'll look into that. As to the drm I've alway had the plugins and they should still be there I think - unless recent updates ( I did one today ) mean I have to reinstall?
Later: haha. all done. I had the default set. all I had to do was tell windows to let digital editions open it and it did. then I found it in the digital ed directory and told calibre about it. calibre put it in the library. now it's safe.
Sorry to bring up this trivia.. but it had me stuck (again).
Thanks for the help.
