Logitech G15 left windows key problem

[Silmano]

I've got a Logitech G15 (the orange one) and since last week I've got an issue with a key don't working at all. The key is the left Windows key one (the right Windows key works).

 

I've checked the following without success:

• I've disabled and enabled several times the 'game mode' toggle to see if it was stuck or something, but it didn't work.
• I've removed the key to check for dust or something under the key, but it was clean (I cleaned the whole keyboard in summer).
• I've used the back of a thin pen to push the gummy thing below the key (where the plastic key actually presses) to see if it works, but it doesn't.

Any suggestion on what to try next? Any idea why could this be happening?

I too have this problem with my G15, Upgrade to Win7 from Windows 8/10, And the button worked before, i did have struggle getting drivers to work not even USB worked out of the box (made the mistake of using a ISO of a original win7 Iso tho,(pre SP1).
