Do you get any error messages? Please provide a full error message screenshot and log file.

NAT42036: 933 Number of steplibs <> number of steplibs on server.

Have you installed latest fixes for the products


Please, can anyone tell me what is going on and what must I do?

This is something for the support. I found similar issues.
Check for example whether you have a library twice in the search order, which can be the case if you have the current library also defined as steplib.

Try this:

  1. right-click on the library in Navigator view (not server-view)
  2. Click on properties
  3. click on Natural then Security then Steplibs
  4. click on ‘update steplib definitions’
