Can't Start Tekkit

[SolarisTiger]

My problem is the launcher works just fine, it updates tekkit, the little FML window runs and validates everything, but then it just freezes, stuck on either the mojang screen or just a white screen and says "not Responding" and forces me to close it. I've run it as an admin, run it in compatibility mode etc. still nada

Please help ._.

Could try deleting Tekkit and downloading it again.
