I found some files that were missing when I FTPed them to the website.
I transferred them over and have been able to proceed with installation.
After unzipping files on your local computer can you just FTP everything in that directory without fear of overwriting directories that already exist. I am using FileZilla and have done the individual directories files each separately - thus my missing a few of those needed files. It would be much simpler if you could just do the whole unzipped file structure along with need subdirectories.
