Issues with OG razer mamba wirless.

Hello, im here because im having some troubles with the og mamba. As i've seen razer's site isn't sellingi t anymore, and probably that's what is causing my issues, but sincerly, after i've spended 170$++, i would want a Top Tier mouse, not a mouse that only causes problems. Dunno when this started, but some days ago i've found out that synapse 2 isn't detecting my mouse. I also have a blackwidow v2 and some man o' wars that work fine. Wouldn't want to trash a mouse like this so im here to ask for some help. Thanks for your time!
