a have the similar problem, tried what u said and it works. Thanks very much Jorcer. Do u have any idea why is that doing?
I recently upgraded win7x32 to win7x64 because i bought extra ram specially for tekkit.
And i see that many people have problem with that luncher.... is that something wrong on technicpack.net ?
anyway its working now thanks again Jorcer
