We bought a SteelSeries World of Warcraft MMO Gaming Mouse. About a month ago we lost the files somehow on the computer or maybe they are just gone. Can't delete the program for the mouse, can't open it to change anything. And the mouse sometimes doesn't work in WoW. We have tried reinstalling the files directly from the site, that didn't work. They had directions to remove from computer, that didn't work. At our wits end. How can we fix?
