Software Update not working

Software Update refuses to work on my iBook G4 (10.4). I open it up, it shows me the window and the progress bar makes no progress. I have tried reinstalling OS X , and I have tried manually updating to 10.4.1 with no new results. Anyone else have this problem? Anyone have any idea how to fix it?

 

I have tried it on different connections, but I have not trashed the preference file. I'll try that right now. Thanks!

 

Well, negative on the trashing of the pref file. It didn't change anything. Anything else to try?

 

Well, here's the thing. My Power Mac has no trouble with Software Update, and it's on the same network, connected to the same AirPort Express.

 

Hey, I appreciate the attempt! I'm stumped as well, so I may end up calling Apple. I just wanted to see if anyone on these boards has dealt with anything like this before.

 

Mine's a little different. When I open Software Update, the progress bar in the sheet that says "Checking for new software" never makes any progress. It gets to about a quarter of an inch and sits there forever, almost like there's no connection. I know there's a connection, because everything else works fine, and it never tells me that there is no connection. I could leave it for a month, if I wanted to, and the progress bar would still be there, having not moved at all.

 

I am very happy to report that the 10.4.2 update fixed the problem. I don't have any idea what was wrong, but it's fixed now, so I really don't care.
Thanks for the help, everybody.
