Big.H, hello. I received your message. Unfortunately I don't have any suggestions. Our servers are hosted like almost all other servers. The only difference that I can think of between servers like ours are the number of people on the server.
Do you get disconnected from CTRA servers because of the high number of people on there? If there is a difference between CTRA servers and *some* other servers, that is the only difference that could have an effect as far as I know. That and the fact that we are sending InSim data where most servers don't use InSim programs.
If there is a problem at the CTRA end, I can assure you that I hear about it very quickly. When we receive "mass disconnect" reports, then it is likely that there is a problem at our end. When one person is having connection problems but nobody else is (as far as I know, this is the situation right now), I am confident in saying that the problem is at THAT end, not CTRA's.
