Has anyone else had problems with lan games using some of Ubi's newer titles? My roomate and I have tried RainbowSix Raven Shield, and Splenter Cell Chaos Theory. Neither of them will let us connect. Usually they lock up as soon as we try to host/join. I was using a Microsoft router, but now we are using a linksys switch with no internet. Neither setup has worked, but both work for our other games. Any thoughts?
