It was because I was trying to use it in the house, I believe. Everything is working like a charm, now. No problems at all with the trainer! Thanks so much for all your hard work.
Sorry I did not want you to feel stressed. I only wanted to say what's working in my case and if not what i've done while i did it to find a problem if others have the same issues. All other options work perfect as far as i can say.
Thank you DDS.
