At a minimum it needs an improved diagnostic. It's occuring with two large documents but I have no idea if it's the same underlying issue. I'm not sure on distribution rights on one document so attaching just the other. it's too large to attach directly so here is Google Docs link. Thanks for all your work on this great product.
A more detailed error should be visible in your errorlog.txt file. You can find it in the "%APPDATA%\NAPS2" folder. For example, if your user name is Tony, it would be in "C:\Users\Tony\AppData\Roaming\NAPS2".
I'll look at the file later.

As an aside. Is there any possibility that NAPS2 could directly import PPM files?
pdfimages is able to extract the files (all PPM) from the above two pdfs, so if NAPS2 could directly import these files it would provide an alternative when the direct PDF import goes wrong (obviously conversion to JPG is problematic as it's lossy).

For the first issue ("unexpected character"), it looks like the PDF file is technically invalid. The program that created it didn't check for division by zero and put in some bad data. I'll see if I can make NAPS2 ignore the bad data (like I assume Adobe Reader does).
For the second issue ("null reference"), I'll need a sample PDF file. If you click my name on this site, you should see a "Send Message" button you can use to send me a private message with a link to the file.

I opened a new ticket for the above.
I have the same problem here.

I sent you a messga with link. LMK when you've downloaded so I can delete. Thanks for all the help!
