Thank god for the Internet!! I too had trouble getting this thing fired up. After purchasing the MiFi and immediately taken off for a road trip I could not for the love of me get this thing to work.
VZAccess manager installed but did not recognized the hardware half of the time and when it did it would NOT activate it through the Verizon activation server!
note: I was attempting to install the software straight off of the image burned onto the device iteself when you plug it into your USB port and it mounts the image ready to install.

It worked for! this post is done from my hotel room in Taos NM way up in the mountain ! This little device promises to be a great companion to the mac!
