i've purchased winzip online so i could open the pronto files and add buttons, etc to my library for use with the Nevo SL. i think i am doing things correctly by saving the files, then opening them in winzip and extracting them back to my documents folder. but when i open it, it opens with adobe reader and wont allow me to view anything as its "not a supprted file type".

any suggestions are greatly appreciated, Thanks - Christian.
