Athanase you need to reset to default. If it still doesn't work you will need to download the default Evolve theme. And make sure you tick REPLAY. I had an issue on two of my DNA75C devices and all I did was save the configuration of one of my devices that did work and then reloaded it onto the problem device and all was well. Does this make sense?
If you are still battling give me your email address and I will email you the config file that worked for me.
