cannot log in

I am VERY new to wordpress and was very happy to finally upload the files to my server, overcome the initial error message and being let to the installation button.after filling out the fields and clicking”install” I got this error message.(this is only part of it)
However, at the end it says I am installed and I am given user name,password etc and a log in link. When I click on the link I am back at the initial page being asked for blog name and email address….and the same thing starts again.
Thank you for your help Claudia
