Dreamliner787300

First of all, I am very new in this field and do not really master computers and windows. I do not know either if I am asking my question in the right place, not being English speaking. I try to understand. I first bought, installed and used Tower 3d pro. It was working fine and I had managed to use speech correctly. So I decided to buy add ons. So today I bought real trafic, LFPG, and real color for LFPG. I installed the 3 add ons. On restart Tower 3d works, LFPG is installed and real color for lfpg and real trafic too. Unfortunately the recognition and speech system no longer works. I no longer hear the requests of the planes and I no longer know how to communicate with them by the microphone. When launching tower 3D in the "settings" tab when I try "test recog" and "test speech" nothing happens. Can someone help me please? Thank you very much and I am very sorry if I am surely the 100th to whom this happens and who asks the question. Thank you for your patience.
