We had this problem with 1065s. We had to uninstall the 1065 module and then reinstall it. If you haven't worked on any of your 1041 clients then this is fairly easy. Just go to Start (on windows), Control Panel, and then Programs and Features. Find ProSeries 2019, double click and it will open up the uninstaller. Select only the 1041 Module. Then when you open up ProSeries again go up to the Update tab and Select and Download New Products. Now you just select 1041 and it will only install that module. 

That's what worked for us. We didn't even have to transfer the data again.

Hope this helps!
