Parse error when installing

I am having problems installing WP on my site. I don’t know why, as I’ve installed three before. I am getting

Parse error: syntax error, unexpected $end in /home2/<domainname>/public_html/blog/wp-includes/version.php on line 14

How do I fix this? I’ve tried re-installing several times, but each time it gives me this error. I’ve tried re-downloading, then reinstalling, but to no avail.
