Blackwidow Elite ALT problem since last update

Hello guys, So a few hours ago today, an update launched for my Razer Keyboard. After that, I noticed that the ALT key was not working since ALT+TAB was not working, after a while a lot of strange things happened like if I double clicked on an icon on my desktop I would go directly to the item's properties. After some research I discovered that this only happens when the ALT key is pushed while you do the doubleclick. So I cleaned it up for a couple hours getting all the keys out and washing them as well as the plate. With the cleaning done I plugged it in and tried again... and the problem persists. What is interesting is that the problem persists even if I unplug the keyboard and I plug in a different keyboard. I also tried to see with the Demo Mode if the key was still jammed or something and no, that does not seem to be the problem. In conclusion, after the last update (or at least, coinciding with it) when I push once the ALT key it stays pushed even if I unplug the keyboard and put in another one. Is there any possible solution we can try? Best regards, Alejandro
