I have a new ASUS p4b-266, 2Ghz, 512k ram Samsung, 80Gb-(8Mb cache) WD hdd - w/only 3% used. When I go to install reader rabbit Toddler v.3.0 it says I need more space on the hard drive. I have over 70Gb available. I can install other apps. I tested for virus using Norton fresh from the box with no updates.
