Game crashes web player and freezes stand-alone on network connection

When I add code for a time limit with a countdown to be updating to the scene it seems to crash the game when connecting top a network in web player, and not all the time but most of the time crashes stand-alone and the Unity Editor. Could this be too much for it too handle? Do i need to connect before I load this scene? I need to know the problem before making too big of changes and realizing it is still not fixed.
