Okay. To set facts straight, iC is not an InSim library, but an open source cruise server application. It uses LFS_External library to talk to LFS via InSim. I cannot find any specific information about the version of LFS_External this application uses, but it looks like it's v. 1.1.0.0. This is quite outdated version which doesn't support InSim packets introduced in LFS 0.6B.
As far as I've heard the updated LFS_External is rather buggy, so the only real solution is to switch to InSim.NET. Unfortunately you'd have to rewrite a big portion of the application to do that.
