I finally found a Freeware program that allows to open,
edit and save PDF's.
Only downside is that it will make some mistakes in the graphics( At the Cat SX setup it won't show the blue parts)so you will have to edit a prefilled setup to know what you are writing.
Opened in Adobe reader everything is then shown in full beauty.
