Ok, I stepped on my Nomad early in the morning when the phone rang (a damn tele-marketer to boot) and cracked the screen. I really never had any problems, but it became annoying. I ordered a new screen off of E-bay but had trouble getting it off. I got mad and opened it up and popped it off. Put everything back together but now the controls won't work AT ALL. No start, a, b, c, x, y, z, up, down, left, or right. Any ideas why? It looks like I put everything back together right, I hope...
