Brett, Another thought is to point your Teradata Studio to a clean workspace. You will have to create the connection profile again. Create a new workspace folder and call it tempworkspace. Then, exit Teradata Studio and bring up again with the -data option and provide the path to the new workspace folder. For example, -data C:\temp\tempworkspace. Let me know if that helps.
