Hi, can you please provide more details on the issue you are having?
1. What version of TDM-Mainframe you are using?
2. Steps to reproduce with screenshots.
3. Any error messages with screenshots.
4. The file you are trying to convert.
It may take some time to troubleshoot this over the communities page. Can you please open a support case by going to CA Support Online - CA Technologies or Contact CA Support - CA Technologies ?
We can post the resolution here once the case is closed.
Best regards,
Taylor
