[Not able to access db after upgrading openx]

Hi,

I tried to upgrade revive adserver with the latest version.

Upgrade seems to run fine and am able to get the login page.

But in order to login I need to reset password for my user.

While trying to reset password, upon clicking on password reset link which I received on my email, I am getting following error

```

An error occurred while accessing the database

Due to a problem with the database Revive Adserver couldn't retrieve or store data.

```

Any suggestions ?
