Don't do anything. Keep the window up, don't click on it, and let it do it's thing. It's gonna freeze, but clicking on it will usually make it worse. On occasion, if it takes like over 5 minutes to unfreeze, you can click on it, the window will get a white, translucent thing over it, then click x. A thing will pop up that says: TheAetherlight.exe isn't responding. Would you like to: Try to restore the program, Close window, Wait for the program to respond. Click Try to restore. If it doesn't work, then click wait for the program to respond. Patience is key.
