Hi, this log says that the file .technic/tekkitmain/bin/lwjgl.dll was not successfully downloaded during startup. This is generally some sort of permissions issue with your local system preventing this from occurring, usually minecraft does not have the ability to write to the hard drive. As a general rule, this is prevented by overeager virus scanners but if you claim yours was off, then it may not be that.
One thing I'd try is turning your virus scanner back off, deleting your .technic/tekkitmain folder and trying again. It could be that your virus scanner previously prevented lwjgl from downloading and minecraft doesn't realize it needs to try and download it again.
