Decided it was time to upgrade firmware (3.0) and maps (2.xxx). Followed a youtube on this process and everything went swell until testmode_v2.3 started copying the device's files/folders onto the 16gb sd card. About a minute into the copy process I get an error message that says cannot copy 'ucominitcomm\' : access is denied  I tried different sd cards, different sources for testmode_v2.3 and even different rar utilities, they all end at the same screen.  The resulting SD card has 13 of the 18 files/folders from the pioneer source drive.  Any suggestions on how to get past this obastacle?

Thanks in advance.
