Here are 4 pdf that i cannot read on my M92 :

They come from a french website (
www.siteduzero) of tutorials, and you can download them in pdf (free) or epub (not free).
First pages are ok but after about 10 pages, all is blank except the header. I try several settings (page, marge...) but i cannot solve the problem. I also try Calibre to convert file but i cannot obtain a good result. What can i do ?
