Has anyone had a successful upgrade from 2.0.13 to 2.0.15?

I have tried multiple times, following the (brief) instructions:

- Copy the content of the htdocs/ folder over your existing installation after having deleted "mainfile.php" and the "install" folder.
- Delete the following folders and files (they belong to your old version and are not needed anymore):

class/smarty/core
class/smarty/plugins/resource.db.php
- Empty the templates_c folder (except index.html)
- Upload the upgrade folder to your site
- Ensure the server can write to mainfile.php
- Login using an administrator account
- Access <your.site.url>/upgrade/ using your browser, and follow the instructions
- Write-protect mainfile.php again
- Remove the upgrade folder after use

After following the directions I just get the white screen (I know this is no help to anyone trying to help). I am just wondering if anyone has had success and can please reply with a post detailing what they did?
