Having problem with my Razer Mamba, please help!

Hello,

So I been using this mouse for a while now and been doing ok with it but a few days ago these issues started happening. The mouse would be unresponsive when I startup the computer and I would have to press the mouse buttons like 20 times before I can get it to work even though the mouse light is on. Second thing is, it doesn't save my settings. I have the DPI on 1200 but every time when I startup my computer it gets reset back to 1800. And it never did this before. The polling rate also gets reset back to 500 when I have it on 1000. I seriously don't know why it's doing this, maybe you guys can help me? Thanks in advance.
