So today once again I encounter this problem, I started the Item Assistant and nothing happen, I check at task manager it show that the Item Assistant suddenly closed itself without prompting anything. Download and installing the latest update also wont help.
But, the trick to start the assistant in older version still work, once the older version has started and minimized to taskbar and then launch the latest version, It work again. But starting directly from the latest version will not work.
Any ideas to fix this issue? What I remember from what happening in the past and yesterday is before the day it happen there is a power outage in my area, and the Item Assistant is running when it happen.
