upgrading 3.6.0 gold to 3.6.0 gold ?

Hi.

I have upgraded my VBSEO from 3.6.0 gold version before 3 ( or 4 months ).
Few days ago, i have received email from VBSEO that i need to upgrade my version to the latest version. Because there is a Bug in current version.

Now , Please tell me which version i need to download and upload to my server ?
Should i download and upload the same 3.6.0 ?
I can see this was updated on 11 March, 2011 on VBSEO website.

vBSEO 3.6.0 Gold has been released on March 12 , 2010 so it is impossible for you to upgrade 3.6.0 Gold 3-4 months ago

Hi.
May be i am wrong...
I am trying to login to VBSEO admin panel. But the password is wrong.
I copied and pasted the password from config.xml , but i am getting the same error.

I am also getting this error while trying to login :
Note: Your config.xml is not writable. Settings cannot be saved.

While my config.xml is CHMOD 644

666 is writable.

The hash in the config file is not your password.

Blank out that value and then go to vbseocp.php and it should prompt you to save a new password.

Thank you.
Should i keep the Config.xml 666 chmod all the time ?
Is it safe ?

or should i change permissions to 644 again after saving settings ?

You should change to chmod 644 when you are done updating your settings
