I found the problem with colors: I was using bindtexture(..) inside my printing code and it was messing up the colors.
But still noone besides me can see the text on the screen!
What possibly could be the problem???

any number of things. do nehe fonts work for the people who can''t see your fonts?

The fonts I''m using are exactly like in the tutorial ( or I am missing something..).I am translating -0.1f into the screen, maybe on some computers it is to little and thats why they cant see the text?? I''ll try translating by -1.0f into the screen and ask my friend to check again on his computer..
