I've been using EG running custom tasks in Add-In. Sometimes I was running a task, it stopped in the middle and an error dialog jumped in the left upper corner. I had no idea what it is so that I just uninstalled EG and installed it again. Then the problem disappeared and the task was running again. However the exactly same problem will happen a couple of days(or shorter) later, which means I have to reinstall EG again. The detailed of the massage is:

Anyone has any idea? Thanks a lot!!
