This key above the media keys is not responsive anymore, it used to open Windows Media Centre when pressed. How do I fix this?

Media key? That sounds like something on your keyboard - as it is NOT at standard key.

If that is the only special key that does not work right, it may just be the key's contacts. If other special keys do not work, it may be the keyboard, or the driver. You should check the keyboard maker's site for drivers.

Yes, it's the key that would usually opens Acer Arcade. However, it would open Windows Media Center before, which has stopped. I need help on how to set the key. It's not in the Launch Manager as those keys are for the internet, email and e buttons.

You need to check the manual because unless someone has the same model, we would not know. I found this Aspire 5920 Series User’s Guide » Gadgets Manual.

Yes, I've read the manual already and it says nothing about setting what the button does.

Well, if Launch Manager in your manual (around pg 39) is not what you need, then you may have to contact Acer, unless another Acer owner comes by and knows the answer.

I reinstalled Launch Manager and it's all working now. Probably something to do with the registry.

That's good news!

Probably something to do with the registry.

Or a corrupt file, or both.

Thanks for the followup!
