I had a problem with my Humax a few years ago and I just loaded the original humax software again and it cleared my problem, im not saying that this is the answer to your problem but it worked for me. As you probably know you can get all the best Humax software on Tuxonhumax website. There is a newer version of Hot fix than you used above maybe that would be better next time. You can find it on Tony Doe downloads ?? A question for you ? do you know where I could get hold of the Mr Dude toolbox ?? any link I go on it is not there ??
