[Smart RGB 700W]

Hi,

About a year ago I bought a Smart RGB 700W Power Supply.

Few days ago the light locked on the lightblue color and the next day the light stopped working.

Now I tried to see what's wrong but all seems fine and clean.

The fun works, just the lights doesn't.

I resetted the pc some times, do I have to download any driver or something? I tried to download Tt DPS G app (i thought it may helps) but when i open it says '' could not set up a connection with power supply. Make Sure your toughtpower DPS is successfully Connected to computer via usb. ''. 

I also tried to press in all the possible ways (click, double click, long time click...) the button but nothing...

What should I do? Thx in advance.
