Invoice not created automaticly

[bpluijms]

Hello,

I am using VM 2.0.10 with Joomla 2.5.6

I have disabled Invoices automaticly send by e-mail to a client.
When using VM 2.0.8 there were still invoices created in the backend. I could print them directly by clicking on the invoice icon or on the printer icon.

Now with VM 2.0.10 the invoice icon shows a red cross and I can't use this print icon (it shows a blank screen).

Can someone explain to me why I can't print the invoices directly from the backend with the print icon?

Thank you.
