Hi
This error stems from a recent change that Salesforce has made on their side in how they respond to certain API calls, in a way that the older pre-v22 DBAmp cannot handle. This is part of their Winter '26 release, and the fix for this issue is to upgrade to the latest version of DBAmp.
Download DBAmp: https://www.cdata.com/download/getfile.aspx?file=free/AFGH-A/setup.exe&name=CData%20DBAmp&tag=Download-dbamp
For more details about upgrading you can refer to the docs: https://cdn.cdata.com/help/AFH/dbampd/Installation_Upgrading.html
You can find release notes here to see what has changed with this version: https://cdn.cdata.com/help/AFH/dbampd/releasenotes.html
Note that the two versions have a different syntax to their serial numbers - you will want to make sure you have your v22+ serial number for this installation
