Need Help with my World of Warcraft Mouse!

Hello, I wanted to make this post because lately I'v been having a problem with my World of Warcraft Gaming mouse. I'v had the mouse for almost a year now and I'v had problems here and there that were easily resolved but this time my mouse isn't working at all! I was playing WoW and it randomly disconnected in mid raid. This has happened to me only once before but all I had to do is restart my comp and it worked fine, this time it didn't work. If anyone has any idea of what I could do it would be greatly appreciated.

Thanks
