Categories in front end and Language

Hello,
i'm using flexicontent on my joomla site, and i have 2 issues :

1: The first one is that, when i'm on the frontend, i can't select a second category for an article :

As you can see here, in the assignement tab, the option secondary categories is empty, and i can't click on it .. But When i create / edit an article in backend, this tab and option work perfectly fine ! I don't know what to do

2: My second problem is that my FlexiContent is in english, and i don't know how to change his language ! I would like to change the language to french, but i didn't saw an option on the configuration panel, and don't know where to look

1 check your acl for this user
2 download and install it www.flexicontent.org/downloads/translations.html

1: Hmmm, what do you mean by acl ? (I'm new to joomla and flexi content, don't blame me ^^)

2: How should i incorporate the language translation package in flexicontent ? Should i intall it on joomla directly, or is it on flexi content configuration tab ?

1 ACL are rules access via joomla go to flexicontent configuration and check it
2 install it like a any joomla component
welcom on board

Nice, it worked, for both my problems !
Thanks for the help

with pleasure
