Publisher 2010 won't save / export PDF nor XPS any more

After updating my system to Windows 8, Office 2010 Publisher quit saving files as PDF and XPS. The error message was:
"Publisher cannot save the file" or in german "Publisher kann Datei nicht speichern".
On a different computer the same file saved as PDF without problems.

I changed my default printer to a different one than before and suprisingly  PDF and XPS export in Publisher was working fine again.
