Any version lower than the current FA version should generally work fine but after installation, the version number is used from the lang/languages.inc file and the version part of the .mo file.

You can compare and use the .po/.mo files from my unofficial repo.

i found a topic concerning this but I can not seem to get it working.
I downloaded the Dutch language file and installed it trough the program itself but the version online is lower then the program and it seems not te be working.
Is there a working Dutch translation available? or how can i adjust the latets English version that does work now and make a translation myself by a PO editor?
This is the first time I work with .po and .mo files so a detailed explenation would be appriciated.

Thank you !

Tom
