I installed Openerp for windows, recently i tried to customize the language traslation.. first, i tried to export a language (english) through csv file and then i edited in my excel.. Then, i tried to imported the customize language to my database n change the language in my preferences.. and afterward, my Openerp become fully white blank page..
