You will require the development snapshot with your version of MySQL. Have you actually gone to /admin/install.php and installed the script?
Maybe you could try uploading the zip and unzipping it on the server. If that doesn’t work you must be getting an error somewhere and I would have to take a closer look to figure it out.
Maybe you could send me access to your server through the contact form or directly to my email which is just ryan@ this domain. If I could modify the files or find an error log I could probably figure out what’s wrong.
