Why aren't my Minecraft Resource Packs working?

Ok, so I got my first PC and I got minecraft and everytime i try to use the Sphax BDCraft Resource Pack, It will load up but then crash when I get to the Mojang Icon and I downloaded the custom map for mine 4 dead and the resource pack is coming up in the gamr but it won't activate.

Are you using the correct version for Sphax and, if you are, are you installing it correctly?

Make sure your placing the zipped file in %appdata%/.minecraft/resource packs. Don't unzip it. I'd suggest using the recommended build if you aren't already. If that fails, try a lower resolution. Select Sphax PureBDcraft from the Settings/Options > Resource Packs menu. You should be good to go thereafter.

Best of luck!
