I have gotten rid of old versions of Limewire by running the uninstall program, then downloading it again and installing it. With the program installed I looked for a file containing zerog and found none on my hard drive. Perhaps that is specific for OS9? Again, I am running OS 10.2.4. I am not sure why any of the comments regarding OS9 should work since I am not even using OS9, and a complete system reinstall of both operating systems did not solve my problem. Any more thoughts?
