I take it you have the PC version?? If so try this command accordingly:
While in-game, hit the 'tilde' key (it's above the Tab and left of the #1 keys), you then should see a cursor blinking at the bottom left of your screen. Now type this:
Here are the ID numbers, just place one of these that matches what (you think) ED-E is after the "player.moveto" command using a space in-between.
001732D0 (Follower Weapon Upgrade)
001732CF (Brotherhood Armor Upgrade)
Hit enter and this command will put you where ED-E is in the game. Then hit the tilde key again to leave the command console.
