With several letter classes this error message may indicate that a required
field, e.g. the sender's name, is missing or that fields are in the wrong
order. Another error message in such cases is "No line to end here". Some
letter classes are very particular about these required fields.
Probably
DIN Brief and KOMA-Script Letter are exclusive.
Use one or the other, Lyx offers KOMA-Script Letter (V.2) which I have
been using for many years.
You will also reach more people by posting in the ENglish languag into
an English language forum.
