I just got my new ACD; and after about 10 mins, I seem to have killed it. I bought the VESA wall mount with it, and started attaching it. As soon I had removed the stand, the block that comes out of the ACD so you could attach the mounting plate to it dropped into the display, and the lever doesn't allow me to pull it back out again.... So basically I cannot put the wall mount on, and I can't put the stand back on either (because I would need that block to attach one of them onto)... Would Apple exchange it for me if I called Online Sales or should I contact AppleCare? Any ideas?
