Razer Cynosa Right Key Problem

Hi, So I've been dealing with this problem for a while now and now it's getting very annoying.

About a month or two ago (bought this keyboard January) the right key suddenly stopped working, as in it wouldn't respond at all. Then it started to act as a Windows Button and a Right Key, so every time I press the Right Key, it's like im pressing the Right Key and Windows Button at the same time, making my screen go crazy.

I've tried everything to fix it, I deleted and reinstalled all the drivers, fully removed synapse and reinstalled, tried using different razer id, deleting all my macros, etc. No avail.

One thing I noticed is that when I disable the right key in Synapse, I'm still able to use the key, though it only works as a Windows Key, but not the right key.

I've also tried plugging it in to a friends pc, and the problem still persisted, but when I plugged it into my MacBook, it seemed to work just fine. I am extremely confused as to what is happening with this keyboard.

Any advice would be appreciated!
