Terrain Assets Error!!

Error while import package: Couldn't decompress package.... ive downloaded it 3 times. reinstalled unity and tried 3 ways of importing it! i need a different download or unity needs to fix this one or something~~~ http://unity3d.com/support/resources/assets/terrain-assets it looks like someone got their problem fixed here http://answers.unity3d.com/questions/54772/unity-terrain-assests-error-importing.html#answer-265706 but that download is down. if someone could upload their own working one to mediafire or something that would be great. :)
