Your installation has not properly finished yet - probably your Member file structure has not been converted.
Can you FTP into the Members dir and check that:
1) A dir called OldMembers is present
2) There's no Admin5.cgi present, but a 00000001.cgi instead
If not, please check if your Members dir has write and delete permissions and try resubmitting general settings.
