I am having trouble completing the install for version 5.7. I make it all the way through and in the end I get a screen that looks like the attached image. If you go to the page it wants to start the install all over again and the same thing if you click the back button.

It almost but not quite finishes. I am pretty sure I am doing everything right and I know that my hosting account is set up correctly because I have another website with 5.7.x on it and running. Not sure what to do here...

Thanks for any help you have.
