Your stream shows lots of points in the past few hours: http://duolingo.com/#/Juanv
It looks like in French and Spanish, you have not finished the first lesson (Basics), so the others are not unlocked. Are you just doing practice? You need to work on the lessons in your skill tree also. I see that your German tree has the Food lesson unlocked.
If your skill points are not updating on your screen, it might be a browser issue. Have you tried clearing your cache?
