Ah hey again,
I'm sorry I haven't answered, my internet went down and you know all that stuff.
Well I got it working just today. I reinstalled and it seems something downloaded wrong (which I've read also can be the problem most of the times) and when I was done I tried open it and it all went fine. Then I closed it and it didn't work anymore. I then turned the japanese off and on again and it all works now (but only when I open it in the folder)
Thank you so much for your help ^^ I'm happy it all works!
