Tekkit Lite will not launch after the first time.

Title: Tekkit Lite will not launch after the first time.

Version: 0.5.1

OS: Vista 32bit, Service Pack 2

Java Version: Up to date

Description of Problem:

If I select anything from the technic launcher to play - Tekkit, Tekkit Lite, Voltz, anything from the list at all - it downloads and runs fine. However, after this first time it will not run again. Even if I literally just close the game, close the launcher, then start the launcher and try to boot the game up again.

Clicking the play button on the launcher causes the loading bar above it to appear for five seconds, in which it displays a couple of things too quick to read, then 0%version..json for a moment, and then it disappears and the game does not launch. Sometimes it says 100%version..json instead, but the end result is still the same. I cannot access the logs from the launcher options either, clicking the button causes nothing to happen.

On a whim, I decided to see what would happen if I tried to launch the game while disconnected from the internet. Here it displays the error message below.
