Nathon

I apologize for not finishing the solution, I was stuck in an airport and my flight was boarding. The .jar file is all that I needed, I had no need to run from command prompt that wasn't an issue on my end

I have a temp solution download and use the .jar file and it will run. This has to be an issue on the .exe client side, especially when it tries to route you to a site that isn't even affiliated with the Tekkit software.

I have the same issue, I will not let me re-install the game even. All you get is the error stated above and nothing in the log file

I get the exact same thing running Ubuntu 12.04LTS
