Razer Naga Epic not working anymore :/

I've been using the razer naga epic for about a year now. I used it in wireless mode when i first got it, but a few months later it was a hassle to keep charging it so I've just had it plugged in directly ever since then.

A few days ago i found the base of the razer naga (the thing you put the mouse in to charge it) and i was like "Sweet wireless mode again"

Now it's not working at all. Even with the mouse directly plugged into any USB port my computer doesn't recognize it, I charged the mouse all night last night but now it's not even being recognized.

I've updated the firmware and im just about to update the drivers, but if that doesn't work im screwed because i dont have the receipt of purchase


Can anybody offer help?
