Hi, i have been using 3.0 with no problems and i've just updated to build 632. Not sure if the upgrade is the cause of the problem but my solo will not now mount any usb drives, when i try it says size unavailable and when i try to mount it i get the crash screen and the box reboots. I am thinking of doing a complete reflash but if its not reading the usb it might not flash from the front usb slot. I have tried numerous usb's with the same result. Any ideas ? cheers
