All I'm trying to do is this;

Similar, not sure if it will help. Try rebuilding master data by going to your-install/install

There isn't actually a template named in the error trace so it's pointing more towards a file issue.

Can you download the .zip again and re-upload the files to the directory?
Make sure you don't remove the install-lock and config.php files.

I was going to suggest a re-install. There looks to be corrupt data in the database or some weird PHP/MySQL interaction. This is something that we have seen in a couple cases, and I believe it was resolved by changing the MySQL bindings in PHP. However, generally, you can't complete the installation with that.

If you still have problems, I would recommend Zend Server in alternative to XAMPP.
I just re-installed it all with a fresh database - lucky i'm doing this locally.

I have one last question I don't think it needs it's own thread though;
where can i edit the css for #logoBlock to make the top background not cover.

I cannot seem to find it anywhere in the template or style options.
