The language file is only complete in English. Some lines are missing in the other languages.
If you want to use it in Dutch you must edit the language.h file :
On line 25 set #define LANGUAGE_CHOICE 11
The Dutch messages are on line 2344 and sq.
You have to compare the English part with the Dutch part and add the missing lines to the Dutch part.
And when you’re done re-upload the firmware.

As all temperatures are on 0 it seems the thermistor for extruder 1 isn’t properly wired.
Be sure to use Arduino 1.0.6 and not later versions.
You’re not editing the language.h file!
You must edit the line : #define LANGUAGE_CHOICE 11
and not the #if LANGUAGE_CHOICE == 1 line.
When, the marlin.ino file is loaded in Arduino you can find the language.h file in the dropdown menu on the right of the tab bar (one of the last items).
And if you don’t add the missing lines to the Dutch language you’ll get an error when compiling.
If you upload the 2 heads firmware and have only one it won’t work.
