AutoIT Script

I need an AutoIT script to be able to save solutions from Cramster.com. Basically there are two types of solutions. User submited: script should take a capture of that in PNG. Expert submited: just right click and print to PDF. This option is only available for paid users. Script should save the files (capture and/or pdf with the problem's number in the apropriate folder - chapter / section folder) Should also handle exceptions like solution missing, should wait for solution to load... etc. Script should be able to download all the solutions of a book.
