Razer Mamba 2012 has button issues

I have a Razer Mamba 2012 that I've been using for several years now, and it developed a problem a couple of days ago. I brought my computer out of hibernation, and the left mouse button on the Mamba doesn't work. The right mouse button handles that now. The scroll wheel is the Right Mouse Click. Everything else seems to be the same. All buttons look as they should in Synapse. I've tried the mouse in a computer that's never seen it, has no Synapse installed, nothing Razer. The Mamba 2012 behaved the same way. Is there way to update the firmware on this mouse?
