Someone Help ingame map problem

I have a LAN network through my house. I have a older computer with nice speed, and i have a newer computer with exceptional speed, but when ever i play ESF Beta 1 on my fastest computer the backround of the is always all messed up. When i don't have the scouter out i just see this giant cube around the map i'm playing, and when i have the scouter out its worse i see the cube and a bunch of colors, and sometimes the 2d skins for the players. Can someone help me fix this?:cry:
