Are you connecting to a Mathematica License Manager?  If that's the 
case, then most likely this is the problem:  Mathematica is simply 
waiting to hear back from MathLM before starting.  Try setting up a test 
license manager on your own machine and see it if works fine.  You would 
have to talk to your system administrator(s).

Another test:  Download a trial version of Mathematica and see if the 
problem still exists.  Trial versions don't connect to a MathLM server, 
so if it starts up, then that's another indication there is a problem 
connecting to your license manager.
