Oh, sorry.

Does anyone have any ideas? Could this be because of the new Minecraft update?

Ok, here's the thing. The game was going all screwy on me, and was displaying a world hole where ever a block not in Vanilla Minecraft was. So, I tried re-installing the Technic Pack. I downloaded the launcher from the main page like before, except now, there are things missing. The options for the Mo' Creatures mod are gone, Rei's Minimap is gone, and a bunch of the graphics options are gone. My computer sucks, and those extra options allowed me to play smoothly. Help? Please?
