Was your core programmed as "hardcore"?  You can switch it to be AA 0.4 if you follow these instructions (which is what I recommend) or you might be able to ignore these messages - not sure.  But certainly changing it to AA 0.4 will get you going:   First put your UM3 into developer mode - it's in the menus on the UM3.  Your machine needs to be on your network (wifi or ethernet) if it isn't already.  Once it's on the network it will show the IP address at the top of the main screen.
