Sadly to say that the white screen that pops up (not the hello) doesn't even load anyway, neither will it actually say "Not Responding".

I have been recently trying to get onto tekkit lite and for some odd reason there is the this random white and hello screen that pop up and then the hello box disappears. The all of a sudden the main screen just doesn't even load and sits there. I was wondering what the problem could be and/or how to fix it.
