From my end, I am seeing that \maketitle is no longer produced. Did you
revert the org/scrlttr2 file after adding the following line?

,----
| #+BIND: org-export-latex-title-command ""
`----

As an alternative you can also do a C-c C-c on the above line and you
will find yourself being questioned with:

,----
| Allow BIND values in this buffer? (y or n)  y
`----

The generation of above query is controlled by the following variable 

,----[ C-h v org-export-allow-BIND RET ]
| org-export-allow-BIND is a variable defined in `org-exp.el'.
| Its value is confirm
| 
| Documentation:
| Non-nil means allow #+BIND to define local variable values for export.
| This is a potential security risk, which is why the user must confirm the
| use of these lines.
| 
| You can customize this variable.
| 
| [back]
`----

You may also want to check that variable.


On export to scrlttr2, Org creates a "*Org PDF LaTeX Output*" buffer
that contains some errors [1].  Inspite of this a pdf file is
produced. The errors are because of extra newlines in \encl and \closing
commands. The attached "patch" to org-latex.el removes this extra
newline. If there is some interest from maintainer's side I can create a
formal patch for org-latex.el[2].

As a side note, if the "to" section of the scrlttr2 file contains a bbdb
link as below

,----
| ** to
|    [[bbdb:Richard%20Stallman][bbdb:Richard Stallman]]
`----


and you have BBDB entry with the address for the above person as shown
below

,----
| Richard Stallman - Free Software Foundation
|          Office: 51 Franklin St
| 		 Boston, MA  02110

then org-scrlttr2 is intelligent enough to expand the snail mail address
automagically.

[2] scrlttr2 is a hack. Nevertheless a clean patch can be applied to
org-latex.el by moving the "\n" to the sectioning options of
org-export-latex-classes.
