Digital Signage

I have a problem I have never seen. When trying to update using software update I get the download, but then the upgrade file will not open and I get a message telling me the file was not expanded because: the digital signage for this package has been tampered with or corrupted since last signed by Apple. Does anyone have a solution to get this fixed? I just have never been here before.
I am running 10.4.2
I fixed permissions
I have not added anything new since the last update.
All else works fine.
It's a Dual 1.25 G4.
