Greetings, friends!

Just the other night, I started up on WotLK Warmane. Seems like a really nicely built private server! My girlfriend and I will definitely be playing for a while here. But I have an issue that I haven't found yet on the forums: my Steelseries WoW mouse isn't functioning as it should. Whenever I try enabling the option for the WoW mouse in the Interface -> Mouse panel, it says that there isn't a WoW mouse detected. Do I need to place the driver for it somewhere in the game's files? Or am I missing something else?

Any help would be greatly appreciated. Thanks all =]
