how to add musketeers to the HRE?

[sakukoivu11]

I am trying to add musketeers to the holy roman empire and I have looked at the add a new unit tutorial but can still nto get it to work properly, I have been able to add the unit, the icon, but when the musketeers show up in the game they have no color or texture there just sort of white colored. How do you add this unit properly? even if the unit has a uniform from milan or spain would be fine
