Hey guys I got a question about the effects of editing in MP games.

I recently started playing with MXvTED v3.0 to change characteristics of existing ships. I made mods to an ISD2 (nothing major just made it a little faster) and I tried to use it in an MP game with my buddies but we kept getting a blue box popping up really fast saying something about network communication problems. I figured no problem and gave my buddies the edited OPT file. Didnt work, same blue box stuff. Can anybody shed any light on this?

Thanks
VM
