I've been running minecraft unmodded on a windows 8.1 machine for a while with no issues. Not used it for a few weeks and now it hangs at the building terrain screen. I tried a fresh install, checked Java is installed and working but still no joy. I'm running Minecraft Launcher 1.6.11, Java is the latest version 8 update 40. Crash Report attached. Would really appreciate any help. ---- Minecraft Crash Report ---- // I'm sorry, Dave.
