Hi
I think you removed all the customization towards User Maintenance screen 95.260.00 from system db. If you want to retain the same customization, then import the customization in to your upgraded version and select your customization level as "ALL Users" Mode and Select the "Exclude the Event Code" Option.
> Then Open the User Maintenance screen 95.260.00 and Switch your screen to Customization mode
> Remove all the DH files module from that screen
> Import the latest version DH File version from SL-Application Folder\DB\DHFiles\APP location.
> Save the current customization and close the screen.
> Un-select the the "Exclude the Event Code" Option now from Customization level.
> Open the User Maintenance screen 95.260.00 with customization
Hope this helps
Thanks & Regards
