A suggestion:
Less dirt and grass, more sand. Dirt and grass should only be on a small patch where the tree and rubber tree spawn, and underground. It should become important to find dirt to establish farms, rather than have it everywhere.
I would recommend updating java, although that is not the problem. This happens when the technic servers are overloaded. Wait an hour or two and three problem fixes itself.
you don't. Just delete all the mods in the modpack you use the lease (for me this would be tekkit lite,) and build a modpack off of that, and ignore it when it asks you to update.
according to you, this page should not exist: http://en.wikipedia.org/wiki/Category:Macintosh_viruses

Use the dev branch instead. There is no support for solder because you are using something that is early in development and still has many bugs. Now stop being a sarcastic little shit.
