gInt Logs - Export to PDF stopped working

Hi

We are using gINT Logs Version 8.2.004 on Windows 10. This has been working trouble free for printing logs to PDF if we use the in-built gINT PDF writer, but recently if I use this option it just generates a 0kb blank single page file. Using Adobe PDF as the printer also used to work but the program would always crash/lock if we tried to save the output to anything other than the auto-generated filename but this approach now seems to go through the motions of generating a PDF but no actual PDF is produced as far as I can tell.

I'm not sure exactly when this problem started but may be related to when we upgarded to Office 365 2016 from 2013, and then had to roll back to 2013 to retain the Adobe PDF tab in Word and Excel. Not sure why this might have broken gINT though.

Cam amyone help please?

Thanks

Tom
