Safe as PDF does't work

Hello Community,

I've installed a Framemaker 2015.

I got a document made by FM12.

If I start a pdf production for a single fm file - it works, but the same for the book, what I actually want, - it fails with a message "can't open first_file.fm ".

In the document some fonts are missing and replaced by default.

What is a Problem?

Thanks for any help.

With best regards,

S
