Tried to upgrade and now site is down

I kept seeing the message that I needed to update my WP. I kept ignoring it but figured today was as good a day as any.
I tried to do the auto upgrade which in the past has worked but today failed. I tried a couple of times, but decided to the manual upgrade. My backup apparently is not good so I am trying to get it from my friend who hosts my site (rubyfruitradio.com). Hopefully, he has one (he should since he hosts for his business.

These are the steps I went through….

Uploaded new wp-includes and wp-admin directories to your web host, overwriting old files.
Upload the individual files from the new wp-content folder to your existing wp-content folder, overwriting existing files. Left the stuff in there and only switched out the stuff in the plugins folder and the themes folders (including index which I think is what got me messed up).
My site went down.
Then I copied over all the loose files like instructed.
My site came back.
However, when I try to login like normal, I get the login and it let’s me put in my credentials, but then it’s just blank.
The address I have always used is http://www.rubyfruitradio.com/wordpress/wp-admin/
Any help would be appreciated.
