oh okay thanks sorry!

The technic Laucher comes up, and i can run teachnic, vanilla and H/M but tekkit won't work the screen comes up and its just white. It's been like this for 20 minutes and i don't know what to do. It will not load. I've tried updating it and java and using developer builds. But the white screen continues. Also running as admin. :c someone help please I'm desperate.
