Panther - Disk Image "mounting Failed"

[bobw]

Create another user and log into that account and download that file and see if you can mount it.

It worked now. Thanks for the help. There was some problem with deleting the files. I guess it worked properly after following the steps from
http://www.macosxhints.com/article.p...31207012226892
Excerpts from the link:
I bought an iBook with OS X 10.3 and upgraded it to 10.3.1. After the upgrade, I could not mount disk images from my hard drive or burn CDs. Apparently this is a common problem after upgrading. I phoned AppleCare and this is what they had me do:
Run /Applications/Utilities/Disk Utility.
Click on “Macintosh HD” in the left column and then press the “Repair Disk Permissions” button. I don’t think this step was part of the solution to my problem.
Delete the file called /System/Library/Extension.kextcache
Delete the folder called /System/Library/Caches/com.apple.kernalcaches/
Restart
After these steps, disk images mount properly and the CD burner works.

Try using Onyx. Under the cleaning tab, clear the kernel and system caches. This worked for me.
