Bakery Module not working: Rather shows an error> Site down..

M using Bakery SSO for my site, having two sections...

Went through the process as per install.txt & also referred to http://drupal.org/node/768458 to go through out...

I was using drupal 6.15, which i updated to 6.19 b4 install on both the sites..

(However, my InstallCentral on my server shows it updated to 6.19 but my available updates page on drupal site (main) shows it is still 6.15)..

Now what i face, when i login from the main section is:

...>>>>undefined call to drupal_goto() in bakery.module on line 1264

The above is not the exact sentence but it is the meaning of the error recieved.. i just simplified it, removing some words in between...

My sub section, redirects to main section's login page, but in the main section, i recieve the above error...

What is the possible problem & solution... Can someone figure it out...
