DJI came out with the new A2 assistant on 08 MAY 2015.  I am currently using 1.4.  I have made sure that I am completely up to date on everything.  I am using a PC, when I launch the 1.4 version everthing comes up as it should, but when I launch 1.6 ... there is no information.  It is like the A2 is being set up from scratch.  I don't get it??  Do I have to reupload to the A2.  Thanks in advance.

Have you completed the firmware updates to the A2 Master Controller and IMU?

Carefully note all your A2 settings if you haven't.

If so, you might try installing the new A2 Assistant on another computer to make sure its not a problem caused by having both versions overlapping.

Can you post a screenshot?
Before you update A2 to latest firmware version, make sure your LED firmware version is 2.1
