Are you using an Automation script that was created with version 1.1? If so try creating a new script from version 2.0.

C:\Documents and Settings%YourUserName%\Local Settings\Application Data\Quest Software\Toad for Data Analysis 2.0

If this does not resolve send me your Automation script and files it uses in private email to
