there is a way to fix it as its only a small error in the translation file
open Lang_Danish.ini (found in Messenger Plus! Live\Languages\) and find the following line (line 936):
code:
EditPosFormat=Linje %1d!, Tegn %2!d!
replace it with the following:
code:
EditPosFormat=Linje %1!d!, Tegn %2!d!
you cant save this file while Danish is the current language however so you will need to close messenger while editing it.
