Yes, I can't sign onto Windows Live either, and Live Messenger wouldn't launch for me either. After trying both, my power button quit working so I couldn't turn the phone off!

I've also noticed every now and then, ActiveSync doesn't recognize the phone and I have to do a soft-reset to make it work. I didn't notice that with V1.

Edit: I figured out what's wrong with the supplied WindowsLive... it's missing an .rgu file, so there are no registry entries for it.

Copy & paste the following into Notepad, save as Unicode, no word wrap, give it the same filename as the .dsm file in the WindowsLive folder but with .rgu extension. Then the included WindowsLive and Messenger will work.
