Ok, So I bought a Jitter modded controller from SilentModz.com about a year ago, when it came everything worked out fine. then i went into a modern warfare 2 private match and found out the controller wont look up or down, but it would look side to side. i tried all different button layouts and nothing worked. so basically everything worked except the right thumbstick, i tried shipping it back to silentmodz and they shipped the same controller back to me that wasnt fixed, it still had the same problem. please help
