I have found following issue yesterday :
The parameter HideInfoText in the FS9.cfg always has to be 0 otherwise TIR will not function !
I have tested several cases and always this parameter produces a conflict with TIR if it is set to 1. So be sure you eliminate this line or you have HideInfoText=0 in your FS9.cfg.
You will find this line in the [MAIN] chapter.
