Thought that I might help development of Drupal 6 by installing the beta, but have already run into a fundamental problem.

Ftp'd files and ran installation script, granting access as stated in the Install.txt file
(ie GRANT WRITE PERMISSIONS ON CONFIGURATION FILE)

Once I ran script it I was directed to "Administer" page where I was told to make permissions on sites/default directory secure, did this and got taken back to the install.php script again.

Seem to be stuck in a loop....can anyone help?
