Getting a Blank page after installing Zen Cart

[musictec]

I've been trying to look in here for a solution to my "Blank page" after I've installed Zen Cart (via my webhost's One Click Install).
I would get to the "System Requirement Page" saying that I have not finished my installation yet and when I click the link, it would go to a BLANK page! Just a white page with nothing in it - no error messages nor anything!

The suggested text says to look at "/includes/configure.php and/or /admin/includes/configure.php file", which, initially, there were no "configure.php" files until I renamed the "dist-configure.php".
However, I couldn't find any details as to what to add to the script of this renamed "configure.php" file to continue to key in my database details and all.

I'm installing this for the 1st time, so this is not an upgrade.
What else do I need to do? I've also tried going directly to "/zc_install/index.php" and that is also a blank page.
Help?
Thanks
