IrfanView crashes when making multi-page PDF

[-.-]

Hi, I used to be able to make pdf from a folder of images but after reinstalling my OS and getting new copy of irfanview, everytime I try now, it just crashes. Anyone know how to fix this? I've tried looking on google and their webpage but cant find anything that helps

hehe... my browser opened up a search after seeing this thread and found me a fix for it
