Yes, I know it's 2019: Razer Mamba 2012 left-click+mouse move does not work

Hello Razer community. Intro: First post here. Had a problem with my Razer Mamba 2012. Problem: When i try to left-click and move my mouse (drag and highlight things) the mouse doesn't work. Also, sometimes, when I single-click things, my PC reads a double-click. Not sure if this is a windows update issue, or a hardware issue, or something else. Tried a wireless Logitech mouse and the click-and-drag works perfectly. So, is this likely a hardware issue? Also, had an old Razer Abysus (probably bought around 2012 as well) and its right click is dead. Question: Can anyone shed some light on this? Thanks! - Tentmaker
