Cant seem to install 10.5.2 update

I clean slated my Mac Mini, had a clean install of 10.5 because of disk space issues and because everything was slowing to a crawl. I backed up my files in my external HD and deleted my internal harddrive and installed a clean copy of 10.5 However, now I try to update my machine to 10.5.2, and it just wont budge. I tried downloading the combo update, when I try to mount the disc image it gives me and error of -4960 When it downloads through software update, it restarts and just trys to install it, but to no succes. I left the mini on all night, and when I woke up it had shut itself down or restarted itself, not sure which one. Any suggestions on what to do next?
thanks!

update:
I was able to fix the problem. After doing some research, it turns out that if your connection times out, or anything happens while the download is happening, it wont be able to mount on the disk. So i just redownloaded it, and walla it works.
