Right click, go to properties, compatibility, check run this program as admin. If that doesn't work, try allowing that program in your firewall, or disabling it. You can also try to go into your task manager, click show processes from all users, find PBlackout.exe and set the priority to high/realtime. I had a friend who had the same problem. If not, go on a mad ass manic clicking spree until it will load lol
