Hello guys, I've had this issue for a while now (at least 4 months,) and no where on the internet seems to have an explanation for me. When I open the launcher, everything runs smoothly, and I can install packs, but when I open them, the bar on the bottom loads the whole way, then the entire launcher closes and then reopens, with nothing the pack not loaded. Here are the things I have tried so far: - Updating/Reinstalling java -Updating/Reinstalling Minecraft -Updating/Reinstalling Technic Launcher & Files -NOTE: I have also went through my computer and deleted all versions of Minecraft and Technic Launcher before reinstalling them. -NOTE: I am running off of Windows 8, and Acer Aspire Desktop
