I recently upgraded (more like downgraded) to Windows 10. I haven't been able to create pdf's since. I downloaded doPDF and worked well for a few days then whenever I went to convert a document is would pop up with the following: "License is not valid for the printer doPDF 8 (error 4380). Print job will be canceled".
I uninstalled the program, then reinstalled and it worked fine again for a few days and then did the same thing.
Please help.

Please uninstall the current version, restart the computer and reinstall the new one. It might be an issue due to the fact that you upgraded to Windows 10.
