I think it's a worthwhile update. The new dashboard is so much better... just updated to 1B13. No problems, but I've been on 4.2 since November. Make sure you're hardwired to Apex and not wireless when updating, also backup your current configuration wouldn't hurt either.
OK I figured it out. . . I still had my wireless adapter running with sharing the same IP address as the Apex. Even though the computer had the wireless disabled the router was still broadcasting to the IP address.
I shut the adapter off and boom the utility ran successfully.
