Yahoo server install: Error 40

[Fullgar]

I uploaded the "upload" file in file "mybb_1408" with Microsoft Front Page. When I went to open the upload file to click on "install" I got this message below. Do I need to call Yahoo for help?? Is this something with how the server is configured?

MyBB has experienced an internal error and cannot continue.

Error Type:
MyBB Error (40)
Error Message:
Your board has not yet been installed and configured. Please do so before attempting to browse it.

Did you go to the correct url? It should be something like http://location to your forum/install/

That is exactly what I typed in:
http://wggray.com/mybb_1408/
It shows the "upload" file. I click on it and get the error 40 message.

When I add install (http://wggray.com/mybb_1408/install/) it cannot find the site at all.
Any suggestion?

I figured it out. *embaresed* it was a dumb file adress mistake I was making. I'm off and running again. Tks all.
