I have a MVP 7500 that keeps freezing about half way through any transfer. I have tried multiple times over wireless as well as USB, and it still does it. I even tried re-loading the firmware, but half way through the 2nd file it froze. I had a page on it, and then when I tried re-loading a page it wiped it out and now it is blank. It has the latest firmware on it. Does anyone have any recommendations?
