The game worked fine after I first bought and installed it. After trying to download replay mod and the files that go with it, I haven't been able to get the launcher to load. It just gives me a grey screen and says not responding at the top. I have uninstalled it and reinstalled it and still the same issue. I have have uninstalled it again and the launcher install has also disappeared. I have tried going on minecraft.net to download it again and when I get to the buy screen to login, the screen is white, and I am unable to continue to download it. I am not tech savvy and have no idea what to do from here. Please send help! lol
