Sorry to add another SQL post to this thread, but I've tried a bunch of methods and it's not worked.

I had a previous version installed, and when i tried to run the googlesitemap.sql, I get this error:

Code:
Cannot insert configuration_key "" because it already exists
I ran the uninstall.sql and tried again -- same problem.

I should be able to figure this out, but no luck. This was through the Zen Cart Install SQL Patches screen. I'm using Zen Cart 1.3.6.
