Hi there, I've tried several times, and it's beginning to frustrate me. But heres the scenario. I have already opened up Minecraft and started a profile with 1.8 and closed it. I run Forge Installer for 1.8, it runs though the motions, but then decides to stop, minimize into my taskbar, and does not finish. Any ideas as to why this is happening and what I can do to get it to completely install? Thanks
