Razer Mamba keeps freezing

Hello, I've been using the Razer Mamba for 2 years now. But this problem was coming up pretty fast after using it but now it really starts to be annoying and more frequent. It keeps freezing on a irregular basis. Both ingame and out of game. The clicking works but the cursor won't move. The only way to make it work again is moving my mouse around like crazy and then it goes back to normal... Does anyone know a fix for this? I've tried some things like changing USB ports, changing some windows settings and switching polling rates but nothing has fixed it. Thanks in advance.
