Hey, I can only assume this is "off-topic" - certainly not a Technic Launcher bug...
Anyway, Typo on this page http://www.technicpack.net/tekkit/
In the section titled "Tekkit uses Bukkit!" The link to "MC Port Centeral" is spelt wrong.
Could this be a problem with the load order of the plugins?
I think I remember previous issues on linux/unix based where the name based load order is ignored?
