I cannot install the zc_install to the server because:-
1. For some reason some files won't upload
2. Because if the upload still goes then I get the red header on the main page (http://kmegd.com) and a big red warning square on the Admin page.
3. I have followed through with checking folders on both new and original (1.3.9h)
4. I have checked that the details for the new database name is in place on the configure and configure.php files.

SO I am now left with a big question:
How on earth do I upgrade?

Please advise - appreciate any advice/help given.
Thanks in advance.
