Having the same problem here. Seems a large group of EADM users are experiencing this, EA has aknowledged that they have a problem and that they are fixing it, they've been trying to do so for 3 days now.
Head over to EA support site and read the following thread: forum.ea.com/eaforum/posts/list/90/306577.page
damn forum system won't allow me to post URL's (You are only allowed to post URLs to other sites after you have made 15 posts or more.) WTF is up with that, just trying to help.
Well the thread pretty much sums it up, they've even created a facebook group: "My EA Download Manager Doesn't Work" - I kid you not.
Too bad really, just discovered
TG about a week ago, and I've been having a blast playing with you guys - really is the way BF games are supposed to be played! Hope to get it working soon
