[SOLVED]Warning: couldn't find charset .. locale en_GB ...

I installed the new Mageia 5 Gnome making a cd-installdisk from LINUX FORMAT's Summer 2015 dvd coverdisk. I am a Finn and have a Finnish keyboard and the installation went well and Mageia 5 seems to work well.
But the Terminal did not start what ever I did from the Gnome desktop. "That happens" so I installed an other terminal program Xterm and started it with the result:
Somehow Mageia has lost my administrative password although I had already successfully used it when starting MCC
The easy way is to download the Mageia 5 install DVD and install again. But is there some other thing I could do
