Carnivores Saga Account and More on Cityscape Multiplayer

I recently made a Carnivores Saga account, so hopefully I will be able to get some people to help me with our Cityscape multiplayer problems, and better yet, get some people to join us when we play. After playing today, we experienced similar sync failure messages while playing death match, and were able to play Co-op for a short time before it completely kicked us and locked us out. Every time we tried re-join the server, it would fail while loading. Also, the person we were playing with was the only person who could host the games, because when we created the games, he couldn't find our server. If you have any suggestions, feel free to comment. Thank you!
