The tool (Here is his description: A dark grey or black knife. think of the texture for the iron knife or the athame in tekkit, and then make it dark grey or black.)
He is having an issue with downloading the pack. That means this is the right section. Tsk, tsk...
OP: Try redownloading (with your antivirus and firewalls off) and see if that helps.
There is a known issue with the exe for some people. The only solution atm is to use the jar file. There is no Tp that comes with Tekkit/Technic, but the one you are using is Sphax BDcraft. There is a post on these forums that gives instructions and a download.

1. Use the edit button next time.
2. I don't understand what your problem is... Does the jar work or not? If it does, this is the wrong section. It is also not an issue with the mod pack, it is an issue with your texture pack.
