Details of the issue After exiting a saved world, cannot log back on or create a new world. The load screen goes through the regular process but gets stuck at 0% when loading the world. I have reinstalled the modpack, and I have reinstalled minecraft. I also have latest Java and latest graphics driver

and latest graphics driver

Perhaps you have this installed already (as the post has a few days on its neck), new release 1st of August (though this is most likely not connected to your issue)
http://us.download.nvidia.com/Windows/398.82/398.82-desktop-win10-64bit-international-whql.exe
(I always recommend to do a clean install - at install, select advanced options and then check the box for clean install - mind that if you have tweaked antyhing those changes might get reset)

I also have latest Java

You're actually using the bundled java version, at this time of writing it's java 8.51 - make sure you have the latest 64-bit java 8 version installed on your machine (don't go for version 9 or 10, it's not supported) - then follow instructions here to switch from native launcher to jar launcher:

First time you launch after the switch the pack might start without mods, this is normal, just restart the pack.

If it still fails, do a repair of the pack, instructions found here:

If you still have issues - post new log.
