Just did a clean install of 10.5. Now I cannot register any of my software through the preference panel. I also checked software update's installed updates and it lists only 4 updates and the rest as (null). When running software update I also get this message in the console: 1/14/08 7:43:36 PM Software Update arguments=(null) This is my 3rd clean install back to back. After the first install, software update had a problem with the mbp keyboard update. It would not install correctly. I even did a download and install but software update keeps bringing it up as a new install. I did not have this problem previously before I did a clean install. I had 10.5.1 I had alot of console messages so I decided to do a clean install to see if I can get rid of them but now it seems I have even more problems. Any help is much appreciated.
