I'm thinking maybe your computer can't find modpack.jar. Maybe it's read-only, maybe it doesn't exist. I dunno, I'm not on your computer.
I think you're seeing it the wrong way. Serious, good posts, that follow the rules, and aren't written by morons, are NEVER ridiculed. Anyone who would, is always warned. You haven't been around long enough.
Please get off your high horse. You're implying that you're better than others because you use gregtech which is hard, and not EE2, which you deem easy. Please just seriously shut up.
They haven't explained very well. You're supposed to turn off all types of ore generation, except for one. Doesn't matter which, they all work, you the technic team just picked one. The Lexicon was made so that people could use worlds that were already generated, with multiple ores.
Regardless of this, I don't think it'll be coming back. A person willing to put malicious code into his mod is not a person who deserves a spot in this pack.
Mods always have full permissions. Adding them to your permissions system is intended to take permissions away. Prevent them from breaking protection, causing damage, etc.
They're added to your permissions as users, generally named [mod].
Eg. [buildcraft] [Redpower] etc. I'm not certain that's how it works with every permissions system though, so be sure to find out.
