full blown 3 wont let me update software

Two things the biggest problem is our hog 3 at the shop is running version 3.1.3 I think something like that. Well we have tried multiple time to update the software in it and its telling us that its not seeing it on anything we put in it, usb or disk. I know that both the usb drives and the disk drive is working because I can load shows from them. and its way past due to update our software to its been almost a year. But I have checked the name to make sure it says what its supposed to and it does and advice? Also when I hit the tab button on top to open up the manual the manual wont open it just does nothing now.
