MacBook with OSX 10.5.1

I know I need to update my software so bad but:

1. When I do software update it says it can't connect, but I already figured that out not a huge problem.

2. I made a new user because my old one was messed up (couldnt open system preferences without freezing, slow, stuff like that) so I want to transfer all my files from my old user (administrator) to a brand new one I just made (which is also an administrator) and delete the old user, how do I do this? Because right now I can just copy and paste old files from the old user to the new and it is taking up crazy space on my HD cause some files I have two of, like my iTunes.

help me out! thanks!

Try a CUT (command-x) and paste. Cutting deletes the files from their original locations and moves them to the clipboard.

From your post, if you have the Leopard install DVD, suggest you boot from the disc, repair the Hard Drive and do an archive and install. This will place a new Leopard OS on the machine and your files etc should be in a folder named Old System or similar. After transferring what you want, go to the Apple web site and download the OS X.5.8 combo updater.
