Just got the UM3 2 days ago and after 2nd print the um3 is no longer connected via wifi anymore...tried to reconnect and no luck. Tried to use usb stick supplied since i couldnt transfer file vis wifi and the usb stick does not open to allow me to choose file when inserted into um3. Rather disappointed $3500 later and only on its 2nd day. Tried rebooting printer and mac pc....any suggestions or help please!...Peter
