OSC not working after upgrade

Hi
right so today I got all my H4PC machines out and did an update from 3.1 to 3.31 (latest) and now OSC doesnt work it recieves clock info and button lights but doesnt send anything to the machines , I also have a wireless windows tablet running H4PC that is working fine , I have tried changing to talk to one of the other machine IP's and nothing , been through everything and my Ip setup is still the same as it has been only thing that changed was the software version
