Blaming? Who am I blaming? And yes, installing the sound failed. I tried again, I checked my connections, rebooted the TIU, cleaned my test track, rebooted my laptop. Installed the MTH Loader ver.5 on another laptop, with the same results, so yes. All in all about 25 attempts to change out a different sound file. Not sure how your coming to conclusion of me blaming someone. After a few failed tries, I will keep trying, as I have done this successfully before with other engines. Though I'm not an expert English writer, I hope I have not offended someone. I'm to look over my spelling and wording to see where I blame someone, can't find any.
But thanks for your input.
