Translated ApplicationResources.properties lost after update

Translated ApplicationResources.properties lost after update

I know it is very stupid. I installed build 5011 after making a backup of the data. After starting the services I found out the interface was english again. Gone hours of translating. I didn't have a backup of it.

How will updates be aware of translations in the future? I mean wilt it automatically keep de translated file active, how will new expressions been added to the file (I do I know which I have to translate)?

                  New to ADSelfService Plus?
