Rename 'Users' module

Hi everyone,

I have been trying to rename the 'Users' module without success. I go to Admin -> Rename modules but the 'Users' module does not appear so I can't rename it.

Actually, what I need is to rename my 'Contacts' module so it is called 'Users'. That's why I need to rename the 'Users' module to 'Sugar Users', so both module names do not collide (if I rename the 'Contacts' module to 'Users', this module no longer appears in Studio, so this is the main problem).

Can anyone provide me a working solution?

Thank you very much!

David
