I bought a new RAT 7 mouse and it came last week. I installed the program and drivers from the madcatz website. It worked great at first then has steadily gotten worse. It only wants to work for up and down on the screen and no sideways movement. I tried to re install the drivers but when I go to reinstall it says they are already there. When I do a location search it tells me they are in the temporary file. Would somebody please help me as this is the second one of this mouse that has started acting all crazy! All Madcatz can say is they are willing to swap it out. My feelings is because this is the second one there must be something wrong with the way I installed them or something else. Please help me!
