Somehow, when updating my FG installation on Vista using Fred's 6/23 build, I can no longer start Dave Culp's T2C. I also tried a couple of his other planes and got similar results. However, loading up several other aircraft models (both YASim and JSBSim) was successful. Below you'll find my command line (generated by FGRun) followed by the console error message.
