I just purchased formidablepro 2.0.3 and received the license key.
I then copy-pasted the license key into the field “your activation code” in the WordPress dialogue for Formidable PRO2PDF:Activated Forms. The software returns the message “This licence code is not valid. Click here to retry.”
Can you help getting the software to run? It is running on WP4.6.1. WP is running on my Synology server behind a firewall as an intranet.
