As of February 23, the pack will load the launcher, and begin the start up process, but in the 5-ish times I've tried to open the pack, it hasn't gotten farther than pulling up the Mojang logo loading screen for no more than a second. I don't know what the issue is currently, but it refuses to run, so it's hard to tell what's wrong. If it matters, all my Minecraft files are completely up-to-date.
