Hi All. Whenever I run UE4 the world viewport is just black. If I build the lighting and then click play everything is still black and I cannot see nothing. UE4 used to work on this computer but for some reason it does not now. I firstly thought that I may be an issues with the newest version of UE4 so I uninstalled that and then installed 4.9.2 but the same still applies. I have attached a few screenshots.
If anyone can help me out, it would be great!
