2 Desktop 2 Laptop

This used to work. I'm not sure what happened. I even deleted and remade the team. 3 will launch, one the lap top wont unless i try and relaunch it several times. Even then it doesn't respond. I can jump on one and a total of 3 will jump. That laptop does nothing, if i press anything on that laptop, the other 3 dont respond. If i try and restart it while the others are open it will at some point open but be unresponsive. Trying to reload the team while they are all open just says "Reload -" etc., and it still doesn't respond. Sometimes others will stop responding when i reload as well. Not sure what happened as last night everything was fine.
