Good day,
I was having problems backing up my 8310 using DM4.5 and decided to upgrade to DM4.7.
Now 4.7 is not seeing my device

.
I've searched the Internet looking for the DM compatibility. Is the DM4.7 compatible with the 8310? Must I also upgrade the 8310 software also? I'm reluctant to load the new software because I can't backup my current information.
Any help would be greatly appreciated
