Has anyone had issues upgrading the rlink? I got a letter telling me to upgrade or i will lose the time etc off the screen and it has now happened. Ive downloaded the file and followed the guide word for word but when i put the usb in it says usb detected then no multimedia found. Im sure its on the usb correctly as ive had my i.t mate do it again for me but still not working. Anybody had problems with this?
