Brocoli

I've deleted LB and started over, but the problems continue. I've noticed that when I add the new platform folder and click next in the next window where it asks me what platform the games I'm going to add are for, when I click next it stays loading for 2 to 3 minutes to move on to the next window. When adding NES games, it asks me if I want to download Retroarch, I say yes, it takes about 6 minutes and then it gives me an error, it could not be downloaded. Also when I go to load the window to select the images I want to download from emumovies, it also takes about 3 minutes. I hope you can help me please. Thank you.
