I get this message on a blank page when trying to save the status of an order to 'confirmed' on administrator/index.php?option=com_virtuemart&view=orders
(because the paypal token failed to update the completed payment (which is a recurring issue, but nevermind that now) )
QuoteTCPDF ERROR: Could not include font definition file: helvetica
When I click back and reload the list, the order is set to 'confirmed' but obviously something went wrong in the creation of the invoice pdf.
How to solve that error?
Do I need to install a VM plugin font?
I guess you need to wait for TCPDF 1.0.8 to appear here:

Your version number might help too.
I use the 1.0.8 version and I get the same problem with freemono
The problem is not VM. Another plugin load anover instalation of tcpdf library before the VM does.
In my case it was System - DPCalendar plugin
Very interesting hint, thank you.
