Honestly, I have a bit of trouble with those as well ( I am not cpanel savvy so much) so I adapted to creating these pages by opening up the html files that usually come with such things, right clicking to open the source code, and copy pasting the code from the source page, directly into an html source page on my website (using WordPress mostly, or any page that allows html). From there I can adjust words, and upload the graphics that come with the product right into the post.
I use WordPress mostly, and altho it may be a little more work than simply uploading these files to your server, I have used this method many times. I hope you understand what I just said.
