Hello I do have problem. I have p3d v4 777 and 747. I open the operation center in administration mode. when I click to update any of the planes in the notification section of the operation centre the black bar down the bottom goes through really quickly and nothing happens. Does not update. Wondering if anybody knows the problem. I have uninstalled the operations centre and reinstalled it. Deleted the temp folder and the content in the roaming files.
