Upgrading Drupal

I have a site in Hostmonster.
My update prosess:
upload 6.22 files to server-->rename .htaccess to .htaccessbak---> domain/update.php-->get 500 error
This process worked in drupal6.20.
Then I rename it back to .htaccess, I got the same error.
Then when I visit the site, error shows like:
Parse error: syntax error, unexpected $end, expecting ')' in /home7/***/public_html/includes/file.inc on line 1216

How can I update the site?
Thanks

I am having strange problems updating everything in my Drupal installation

Hi everyone,

I did an update of the webform module and I got errors.
here is the 3 errors I got :

I upgraded to D7 and ?q=user no longer works

Is there different way to login to D7?

I just upgraded from drupal 5 to 6 and installed book block module to display navigation to individual books. Although the configuration pages for book block allows me to configure the books into individual blocks and later assign the blocks to the site regions, none of the blocks actually displays in the regions. I tried in the custom theme as well as minelli and bluemarine with no luck. There are no error message either. Any tips on possible ways to troubleshoot this or even code to display navigation to individual books will be very helpful.
