Thanks for being so quick.
Yes the card (I tried even different cards) work fine on any other devices.
I tried hard reset as well (is this from the menu>>Privacy>>Factory data reset???), no change at all.
Astro did not help either (it just show that there is no content avail.)
The only thing I do not get is that as far as I can remember the first time it was ok, I am not sure why it went wrong.
Is there a way to tell the Iconia to boot from the USB, or from a PC?
Because the USB port works fine and if I could choose where to boot from....
I might call Acer anyway see what they say.
